The ClearTest Transformer Tester provides quick and easy tests of de-energized power distribution system transformers. It is a handheld device with a single pushbutton that provides a clear indication of open circuits, short circuits, including shorted turns or shorted windings and confirmation that the test results are OK. The ClearTest is a completely new design that briefly energizes the transformer and takes a snapshot of the transformer condition by measuring the voltage, current and power factor of the test signal.
The ClearTest finds transformer defects that include:
- A single shorted turn in the primary orsecondary side of a transformer
- Open coils or blown internal fuses or breakers
- Partial shorts including shorted turns, shorted turn layers, coil to core shorts and primary to secondary shorts
- Bad transformer ratios resulting from shorted turns
