BENEFITS
Perfect for pass/fail testing – you set the allowable PD
level and the unit determines pass and fail.
Simple to use – 8 buttons on the front panel are all you
need to operate the detector.
Straightforward replacement – if you’ve got an old
analogue unit and need a cost effective, simple replacement.
Multiple detector – with the data acquisition
software you can operate and monitor multiple detectors at
the same time.
Integrated test systems – because of it’s compact design
and functionality this unit is ideal for an integrated PD test
system including an AC power supply.
APPLICATIONS
Testing of:
Distribution Transformers
Power Transformers
Current and Potential Transformers
Rotating Machines
Switchgears
