HVPD On-Line PD
The High Voltage Partial Discharge (HVPD) PDSurveyor is a handheld tool for on-line pd 'surveying'. It provides rapid 'look-see' insulation condition testing of medium voltage plant in the range 6.6kV to 45kV.
A combination of three senors:
- Transient Earth Voltages (TEV)
- High Frequency Current Transformer (HFCT)
combine to give an instant indication of PD activity.
Suitable for PD pre-screening tests of MV cables, switchgear, motors, generators and transformers. With test times per plant item or cable of 10-30 seconds, large-area MV networks can be scanned quickly and easily.
