IGBT (insulated gate bipolar transistors)

admin2020-06-04T10:20:48+00:00

IGBT's (insulated-gate bipolar transistors) are used in modern Uninterruptible Power Supplies (UPS) combining high efficiency with fast switching whilst keeping the frequency output without narrow tolerances. Stable seamless electrical power supply. IGBT provide extremely low voltage distortion and improves the power efficiency especially when supporting...

What is Peak Load Lopping and Peak Load Shaving ?

admin2020-09-30T11:05:29+00:00

Peak load lopping also known as ‘peak load shaving’ & ‘peak load shedding’, is the used when the GRID supply can’t be increased due to cost or location and you need more power than is available. Sometimes the GRID can’t or won’t supply the power...

eBay parts won’t save you

admin2020-03-25T11:58:08+00:00

Does eBay provide your only opportunity for spare parts for aged equipment? Can’t get parts anymore, not even from Ebay? eBay, your last hope for spare parts has failed you? Ever needed parts Urgently? And can’t get them from anywhere? Not even eBay? eBay spare...

Phase Shift – What Is It?

admin2020-07-07T09:04:42+00:00

Phase Shift happens what there is more than one power feed coming into a building. Each transformer supply needs to have the same phase rotation and the identical phase location. (zero) If there is only one supply, then there is no issue. On the other...

The Role of Static Transfer Switches – How fast do They Switch?

admin2020-06-24T13:23:12+00:00

Static Transfer Switches - How fast do They Switch, In the event of a power loss? Power Continuity installations switch seamlessly via STS to the UPS & Generator supplies without any break, to avoid any disruption or loss to your site; virtually instantaneous. No Break...

Power Cuts Reality

admin2020-05-15T10:32:12+00:00

Moorside nuclear power plant officially cancelled. Japanese firm Toshiba said: "The huge loss incurred by one of its UK subsidiaries, was due to writing off hundreds of millions of pounds of investment in the proposed Moorside nuclear power plant, in West Cumbria." Former EDF chief...

Powering a Data Centre – why does the power fail even with a UPS & how to properly failsafe?

admin2020-05-06T08:46:47+00:00

So you've gone and installed a UPS backing up your data centre. Excellent, you may think. Now I am fully power protected. But is that really the case? Whilst it may be true that you are protected against spikes, brownouts and short duration power cuts....

How does a Micro Grid work?

admin2020-04-15T10:46:17+00:00

As briefly described in our other post, a micro grid is a localised energy grid. Generally linked to the main grid. Having the capability to disconnect automatically and function as its own independent grid when necessary. Traditionally homes and businesses connect to the National Grid...

Battery Energy Storage Systems (BESS)

admin2020-06-12T14:16:25+00:00

A battery energy storage system (BESS) is a system that stores energy to be used at a later time. This storage system makes use of battery technology. There are a large range of battery technologies that form the generic term Battery Energy Storage System. Battery...

What is load shedding?

admin2020-10-31T12:19:58+00:00

Load shedding is the operation of temporarily reducing the supply of electricity to an area, to avoid overloading the generators. As explained elsewhere, a generator cannot take 100% of its load in one go. This would cause the frequency and voltage to drop too much. This...

Power Conditioning – Using Flywheel Rotary UPS

admin2020-03-27T12:45:07+00:00

You may well ask how flywheel Rotary UPS provide power conditioning. The exact method depends from manufacturer to manufacturer. As an example, Active Power's fast acting microprocessor and fast voltage transient discharge window, samples the incoming 16.67 msec sine wave 333 times every 50 microseconds....

How to ensure Voltage Stability

admin2020-05-11T08:12:04+00:00

Mains power (as well as generator power) is not totally constant and fluctuates constantly. For most of the time, these fluctuations are within the acceptable range, but from time to time, the voltage fluctuations are greater than the tolerated range and you get power surges...

Power Spike Prevention

admin2020-06-08T11:45:37+00:00

A power spike or power surge can be caused by many different events. Including lightning strikes, power outages, tripped circuit breakers, short circuits or power transitions in other large equipment on the same power line. A generator cannot respond quickly to a power spike. So...

Power Dip Prevention

admin2020-04-14T12:35:51+00:00

Power dips are not full blown power cuts. Power Dip prevention Rather, a temporary reduction in power (often less than 2 seconds). Only an Uninterruptible Power Supply will prevent your equipment from "seeing" the power dip and affecting your operations. Traditional battery UPS will quite...

Brown Out Power Prevention Explained

admin2020-04-18T18:30:12+00:00

Brown out power prevention Brown out power prevention is more important than ever before. As these occur frequently across the UK Power networks. The only way to prevent a brownout (a temporary reduction in voltage) hurting your sensitive equipment is to have an Uninterruptible Power...
