  • ATS Failure – automatic transfer switch (ATS) failures
    ATS Failure - automatic transfer switch (ATS) failures can happen  Automatic transfer switch (ATS) is a device that automatically transfers the electrical power supply from its primary source supply to a backup source, ‘standby power generator’, when the ATS senses a failure or outage in...
  • AMF Failure – automatic mains failure panel (AMF) failures
    AMF Failure - automatic mains failure panel (AMF) failure can happen   Automatic mains failure panel (AMF) is a device that automatically transfers the electrical power supply from its primary source supply to a backup source, ‘standby power generator’, when the AMF senses a failure...
  • UPS FANS – WHY?
    UPS FANS are important to the operational status of your Power Continuity UPS UPS Fans will require replacement at least every 5 years dependant on the working environment of the UPS. This is down to age & wear and tear. What to look for with...
  • Generator Common Faults
    Generator common faults that we frequently deal with during client call outs at Powercontinuity we have listed below. As you will see many of them are either totally avoidable or easily sorted. Generator Common Faults Emergency Stop pressed - again similarly to the UPS, with...
  • Generator White Smoke
    Generator white smoke when running indicates water in the fuel. Generator could be running without issue and then the clear exhaust smoke begins to turn white and then stays white means that there is some water within your fuel system. This typically happens with diesel...
  • 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....
