  • UPS Overheating
      UPS overheating – Why? And How to stop it. Causes of UPS overheating explained: Environment Has the Air Conditioning in the UPS environment failed? More commonly is the A/C still working although not operating efficiently causing the ambient temperature to rise? This will quickly cause the...
  • UPS Overheating – Common Causes
    UPS overheating happens frequently. Power Continuity explain the most common causes. 1. Air Conditioning  Air Conditioning in the UPS environment has stopped working. This will quickly cause the UPS to overheat, go into bypass then stop. 2. Air Conditioning is working but inefficiently Air Conditioning is working...
  • UPS battery failure – Why?
    UPS Battery failure is common and happens. Power Continuity explains how this can be avoided, with careful planned maintenance and by following these simple steps. 1. Operational Temperature The optimum battery performance is achieved if the battery operational ambient temperature is constantly between 19ºC and...
  • UPS Failure – Common Causes
    UPS failure most common causes are: Power Outage lasted LONGER than the battery autonomy of the UPS, hence the UPS died as it had run out of battery stored power The UPS has never been serviced or only randomly serviced. NO maintenance contract in place...
  • Generator Under Voltage – Why?
    Generator under voltage can happen suddenly and without warning. Immediately check the following to isolate the root cause:- Check all voltage sensing fuses to ensure none of them have blown. Take each fuse out , check visually for issues, clean and replace Ensure the AVR...
  • Generator Over Voltage – Why?
    Generator Over voltage can happen randomly , especially when supporting machinery. Carefully check the following to isolate the possible root causes:- Are setpoints too restrictive after full load rejection. Add small monitoring delay. Check the loads are not imbalanced or cutting IN and OUT too...
  • Batteries Overheating – Generators?
    Generator batteries can overheat… Really? The short answer is YES they can. Generator VRLA batteries are designed to operate at higher temperatures than standard batteries. That is because they are close to a generator and are therefore designed to operate between 20-40C. Should the operating...
  • IGBT Explained
    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...
  • Peak Lopping Explained
    Peak load lopping also known as ‘peak load shaving’ & ‘load sharing’, is the used when the GRID supply can’t be increased due to cost or location and you need more power than is available. When the more power is required and the GRID can’t...
  • Generator Frequency Fluctuation
    Generator frequency fluctuation can occur when the generator is under load. The diesel engine can he heard to be struggling or hunting randomly. If this audible fluctuation continues you may find that on the control panel you can see the frequency drop and rise erratically....
  • Data Centre Cooling Air Conditioning Installation
    Traditionally, there are two ways of cooling a data center: air-based cooling and liquid-based cooling. Air-Based The first and most common, method within the realm of air-based cooling is what’s called ‘cold aisle/hot aisle.’ The idea is to separate the cold air from the hot...
  • Data Centre Fire Suppression Installation Upgrade
    Facility managers have a range of factors to consider when it comes to data centerfire suppression systems. The primary fire protection systems used within datacenters typically include: wet pipe sprinklers, pre-action sprinklers, and specialsuppression (i.e., clean agent, inert gas, or mist) Method 1 - Inert gas fire suppression systems for server room and Data Centres -...
  • Generator AVR – What is the AVR?
    The Generator AVR is a small electronic device that sits on the alternator monitoring the power output. You may never even notice it. This small electronic device automatically maintains the generator electrical output terminal voltage within pre-set manufacturers parameters. The Automatic Voltage Regulator (AVR) is...
  • Generator Hunting and Surging
    Generator hunting and surging randomly or erratically. This can occur when the generator is under load and has been running perfectly normally then suddenly your generator struggles. You’ll first become aware of this , because you’ll hear the engine struggling or hunting randomly. Check the...
  • eBay parts won’t save you
    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...
