Uninterruptible Power Supplies need not be daunting. Let’s Help!
100% Power Continuity for your critical systems. Independent Energy Systems that you control.
Generally UPS systems are purchased because there is a requirement to protect the client’s essential supplies in the event of a power failure or brownout.
Having bought the system however, little consideration is given as to how it will continue to operate over the years.
The idea of plug and play conceals the fact that uninterruptible power supplies are highly technical equipment consisting of thousands of sensitive components.
The new uninterruptible power supply system will always come with a manufacturer’s warranty, which would be perceived to offer protection in the event of a failure during the first year.
What is not considered is that although the manufacturer has agreed to guarantee his equipment against failure, it will be repaired during normal working hours and certainly no earlier than the next day, often several days later dependent of the availability of engineers and parts. During this time, of course, the essential load is unprotected.
No UPS = No Protection.
A UPS maintenance contract will offer peace of mind to the client, as not only will the contract offer an agreed response time for an engineer to attend site, it will also ensure that the UPS is inspected and the results recorded on a regular basis. This can be arranged during an agreed operating window of time, which can be tailored to suit the client’s operating requirements, together with emergency 24-7 call out.
The UPS system has a number of components which have a finite operating life. The ones that immediately spring to mind are: fans, batteries, DC and AC capacitors. A failure of any of these components severely limit (and generally eliminates) the Uninterruptible Power Supply’s capacity to protect the essential load.
Regular maintenance will monitor these components and highlight any potential failures, normally in time to take action to replace them and maintain the integrity of the system.
A typical instance on a non-maintained Power Protection system would be that during a utility mains failure the batteries failed to support the essential load for the expected time. The client would require immediate replacement of his batteries to regain his perceived autonomy; the unanswered question would be ‘why did the batteries fail so early in their operational life?’
Without regularly maintaining and thermal monitoring the UPS and its UPS Batteries, one or all the DC capacitors may have prematurely aged the batteries causing a severe reduction in their capacity to support load. Regular UPS maintenance visits would have identified this problem earlier, and by changing the offending components the expense of prematurely replacing the batteries would have been avoided.
Of course, if a UPS system is present, then the next step is to ask yourself:
- What if it fails?
- Do I have a generator standby power system?
- If there isn’t a standby diesel generator, is that due to lack of space?
- Or assumed cost?
Better to ask for a FREE site survey and establish what power protection you may require before your Critical Systems are tested by power failure.
Power Protection – Uninterruptible Power Supply (UPS) or Generator – Which?
Diesel Generators as part of an emergency power system have built in fuel tanks from 8-12 hours, depending on manufacturer. Some have additional external tanks that can extend their running time to 24 or 48 hours.
A Generator has less operating constraints than a UPS System. The generator can be installed outside in its own weatherproof acoustic container. It’s not prone to climate conditions and can run as long as you wish, as it can be refuelled whilst in operation with no requirement to turn it off.
To ensure cost-effective operation, the UPS-genset combination must be designed to ensure optimum economic conditions and compatibility of the technical characteristics. To determine the optimum combination in terms of purchase and operating costs you need to take a long term perspective of your site.
UPSs (Uninterruptible Power Supplies) and generator sets (Diesel Generators) are frequently combined to supply continuous power to sensitive applications such as computers, telecommunication centres, industrial processes, hospitals, airports, etc.
These two types of equipment offer complementary functions for the supply of critical loads.
A UPS provides quality power and isolates loads from upstream disturbances, in addition to supplying battery backup power that can last from a few minutes up to several hours, although in practice a UPS usually has no longer than a 30 minute battery backup, as longer than this it is far more cost-effective to have a backup power generator.
Beyond the battery backup time, a diesel generator (often referred to as a genset) steps in to provide longer protection.
These are the KEY questions to ask yourself before venturing into any power protection project:-
- What is the kVA peak demand of your critical load to be power protected?
- What is the kVA peak demand of your NON critical load to be power protected?
- What is the combined kVA peak demand of your total maximum load to be power protected?
- Is your load likely to increase during the next 5-10 years?
- Do you intend to remain in your building for the next 20 years?
- Or are you likely to relocate?
- If so do you prefer containerised power protection systems?
- What autonomy would you prefer for your UPS systems in minutes?
- What number of hours will you require the backup generators to run OFF Grid ?
- Do you require N+1 for the power protection system? Or even N+2 or N+3?
- Where will the UPS systems be located?
- Where will the generator/s be located?
For total Power Protection we recommend N+1 Power Continuity as minimum.
Once these questions have been addressed then you’re ready to involve PowerContinuity Systems for a full site survey.
Remember – don’t spend anything until you are certain of your requirements.
In addition to installation and maintenance costs, remember to take into account fuel storage, special room conditions, servicing, and access.
Uninterruptible Power Supply (UPS) Power Solutions – What Are They?
UPS power solutions are required whenever aberration of the utility mains supply will result in problems occurring, whether it is loss of data on a server or the failure of life-support equipment. It does not have to be an interruption to the utility mains supply; high volt ‘spikes’ occurring due to the operation of other plant connected to the utility power network can cause interruptions or failure of unprotected equipment.
What can UPS Power Solutions prevent ? Let’s begin with the most common.
‘Brownouts’, while not a total loss of supply, can also affect the normal running of installed equipment, causing it to malfunction due to insufficient voltage for correct operation and also possibly causing overheating. There are other forms of line conditioning which can alleviate some of the problems caused by ‘brownouts’ and ‘spikes’ by supplying a constant voltage output to the operational equipment. What they cannot do is to provide a supply in the event of the utility mains supply failing for a period of time even as short as 30 milliseconds. This type of break is enough for the equipment power supplies to shut down and for the operation of the equipment to fail. So now you understand why you require Uninterruptible Power Supplies, commonly referred to as UPS Power Systems.
To overcome this problem where the equipment cannot stand a loss of supply for longer than 10 – 15 milliseconds we have the UPS Power Solution. The type of UPS Power Solutions is entirely dependent upon the load in question.
At one end of the scale we have the home/small office user, where if the computer failed due to a malfunction caused by the utility mains the operator could lose their data, possibly without the benefit of current backup being available. UPS Power Solutions for this type of operational status would be a line interactive UPS.
During normal operation, the UPS would be regulating the incoming utility mains supply, often by a transformer tap changing circuit, against ‘spikes’ and ‘brownouts’. Should the utility mains supply deviate outside the limits set in the UPS for correct regulation, the UPS would switch the output to its inverter and run on battery until either the utility mains returns within the preset operating tolerance of the UPS or the battery falls to its lower safe operating limit, at which point the UPS can transmit a signal to the computer telling it to carry out a controlled shutdown to prevent loss of data.
The other end of the scale would be a Data Centre where there would be multiple rows of server cabinets. The proposed UPS Power Solutions for this situation would undoubtedly be a parallel ‘double conversion’ UPS power system. The use of a ‘double conversion’ UPS system means that the inverter is on line constantly and requires no switching action as described previously. The use of a parallel system also provides greater resilience to loss of the utility mains supply, as the parallel system would be in an N+1 configuration. There would always be a spare module instantaneously available in the event of either a module failing or being taken off-line for service.
UPS Power Solutions are not confined to supporting computer systems. Whenever there is a requirement for short-term power during a utility mains failure, the UPS Power Solution can be the preferred answer. In some instances the UPS power solution can be used as an emergency supply for opening or closing electrically operated doors; there is no requirement to provide uninterruptible power, just a power source in the event of losing the utility mains supply. Equally, UPS Power Solutions would be suitable for running smoke exhaust fans within a building. In the event of fire the utility mains supply will be turned off, and therefore the UPS Power Solution is ideal for running fans to clear the area of smoke. Again the requirement is for a means of operating equipment for a finite time without the benefit of utility mains power.
The UPS Power Solution on its own is an ideal method of providing a temporary power solution in the event of a utility mains failure. Its limitation is governed by the battery autonomy and is suitable where the equipment it is supporting can be shutdown safely before the end of autonomy, or where the requirement is for a short-term supply to operate vital equipment under controlled conditions.
Let PowerContinuity calculate your UPS Power Solutions requirement at no cost to yourself, entirely free of charge, and get the peace of mind that only preparation can offer.
What is meant by the term ‘Critical Power’?
Critical power is any form of power that, if it were not available, would have disastrous consequences.
What type of places would require continuous uninterruptible critical power supplies?
Hospitals, Surgeries, Military Field Operations, Banks, Airports, Space Bases, Communications Networks, Distribution Centres, Food Manufacturing Plants.
Surprisingly, there are thousands of environments that require 24-7 uninterrupted critical power, come hell or high water.The only true way to protect critical power is with the installation of uninterruptible power supplies, known as UPS Systems, and Diesel Generators.
This system would then need to be made totally invincible to any power outage, however improbable or unlikely. To achieve this, the UPS system and generator system would need to be replicated more than once in the event of mechanical failure. The term used is N+1, and this equates to a double system. N+2 will be 200% cover and N+3 would be triple cover.
An in-depth understanding of how to protect critical power can be reviewed in the section on this website entitled, Disaster recovery and power protection systems
How safe is the critical power at your office or business?
Most businesses today couldn’t operate without their computer servers, so the perception that only hospitals require critical power is rapidly changing. Many now require total Disaster Prevention.
Any business should take the time to have an energy audit. Classify what is critical, what is necessary and what you can do without. Then prioritise. Take steps to protect your critical power before it’s gone.
The assumption that all power is critical power, so power downs will never occur, is naive.
If you need critical power, then protect it.
Firstly, what do we mean by the term ‘Power Protection’?
Everyone, whether a home owner or company director, expects power to be provided by large multinational companies or government owned production facilities for their electrical appliances. Just plug into an electrical socket and the power must be there anytime.
So power protection means the pre-installation of power systems that will, in the event of a power outage, take over from the existing lost supply and replace it with an independent source of power. This form of power protection is usually undertaken by the installation of uninterruptible power supplies which are, in turn, backed up by Diesel Generators.
Electricity is manufactured by many means, although the most common methods are from burning coal (China opens two new coal fired power stations every week, of every year), gas, hydro power (from river or lake waters), nuclear power and most recently wind turbine and solar farms. So, if power is so readily available, why would anyone need power protection?
Sadly, we live in an unpredictable world. The threats of natural disasters, terrorism, fuel embargoes and ageing power plants have forced us to readdress our dependency on electrical power always being available. Today there is a real need to be able to protect your power requirements. Why?
Hospitals couldn’t operate at all without serious power protection being in place. Police and security forces need to protect their power to keep communications lines open, whatever the eventuality. Military forces can no longer operate in the theatre of the world without uninterruptible power supplies and power protection. In fact they need more than just power protection, they require Disaster Prevention.
Power Protection is insurance, allowing anyone or any business to continue as normal, without catastrophic loss of power.
Is power important? Remember the millions who lost power in the US winter of 2004, the floods in Europe in 2005, the floods in the UK in 2007. In every instance, government institutions were able to come to the rescue because they already had power protection systems in place.
Today it is common for even home owners to install some form of power protection.
It’s more common for small to medium businesses to invest in power protection.
No one can work in a factory or office without electricity.
Today, more than ever, power protection is the only way to maintain a functioning society.
Standby diesel generators working in tandem with uninterruptible power supplies are commonly used by major hospitals, military forces, government buildings, data centres, banks and distribution networks as power protection for their critical systems.
How safe is your critical power?
Do you have power protection?
Do you need Disaster Prevention?
Uninterruptible Power Supplies (UPS) – So What Really is a True On-Line UPS?
The best description of a True On-Line UPS system would be a UPS system that did not require any switching action to take place to allow it to continue supplying the load during a utility mains failure.
An example of a system that is not On-Line would be an emergency lighting system; this system uses a contactor to supply power directly to the lights while the utility mains supply is present, and when the mains supply fails the contactor changes over and supplies power to the lights from a battery-backed inverter. There is a short interruption to the load due to the switching action of the contactor.
A True On-Line UPS has a rectifier at its input to provide a DC source to keep the battery on charge and also providing a power source for the inverter. Therefore in the event of a utility mains failure it is only the rectifier that stops working while the DC source for the inverter is derived from the battery instead of the rectifier.
A further advantage of the True On-Line UPS system is that it provides isolation of the load from the supply source. This can be advantageous in the event of a utility mains failure where a generator provides the mains power. The On-Line UPS system provides a known harmonic load to the generator; with a non On-Line UPS the actual load harmonics can be seen by the generator, which could cause it to fail when the UPS returns to normal operation.
Due to the fact that the On-Line UPS is constantly supplying the load, any additions or changes to the load by the client will be highlighted immediately. This is in contrast to a non On-Line UPS system, where the first indication of any load problem would be during a utility mains failure where the generator refuses to accept the load and shuts down, resulting in loss of site load.
Therefore, in conclusion, a True On-Line UPS system provides seamless transfer between normal operation from the utility mains supply to battery operation in the event of mains failure.
In addition, it provides isolation between the ‘Dirty’ mains supply and the load which requires ‘Clean’ power.
