Transformer Testers – ClearTest

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 or secondary 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

ClearTest looks?both inside and?outside the?transformer -?testing the coil,?core and winding?as well as between?the transformer?and whatever it?is connected to.
