Why Measure Partial Discharge In High Voltage/Medium Voltage (HV/MV) Assets?
Measuring partial discharge (PD) activity in your High Voltage/Medium Voltage (HV/MV) assets gives you a clear picture of the true condition of your power assets, so you can schedule your maintenance programme based on actual condition rather than time intervals, saving you both time and money.
Did you know that 85% of disruptive switchgear failures are partial discharge related? Once you have PD present, it will always increase and if left will inevitably cause a failure which may be sudden and catastrophic. PD is the most reliable indicator of the condition of insulation within live assets.
EA Technology UltraTEV Plus² Hand-held Partial Discharge (PD) Instrument and UTP2-WPR Wireless Phase Reference Unit work together to...
✓ Distinguish true PD from noise and other interference
✓ Ensure perfect phase reference / phase-lock every time, through multiple methods (mains power connection, e-field, Rogowski coil and photo-sensor)
✓ Aids connection wirelessly; UTP2-WPR communicates with UltraTEV Plus² (up to 40 metres away)
✓ Keep working as long as you need to with its long-life battery allowing up to 16 hours operation
