HV/EHV Power Cables Can Now Be Field Tested On Site With VLF PD and TD Diagnostic Test Techniques

photo2.jpgCOPAKE, NY – High Voltage, Inc. Field HV Withstand/ Proof Tests with on–site Partial Discharge and Tan Delta Diagnostics is now possible for HV Power Cable classes such as 69 / 110 /132/ 220 kV. By using a High Voltage, Inc. VLF -200CMF (0 to 200 kV AC , .1 Hz Sinewave Hipot) coupled with Power Diagnostix GmbH ICM Flex PD/TD Measurement Systems, useful diagnostic cable integrity evaluations can be made.

By using a VLF source instead of power frequency or resonant technology, tremendous test equipment cost savings and on-site labor savings are possible while obtaining crucial information on these critical power delivery circuits. Cable loads up to 3.75 Microfarads can be tested utilizing one of three test frequencies - .1 Hz., .05 Hz. and .02 Hz.
