Greenlee CT-300 ClearTest Transformer Tester

The ClearTest Transformer Tester provides quick and easy tests of de-energized power distribution system transformers. It is ahandheld device with a single pushbutton that provides a clearindication of open circuits, short circuits, including shorted turnsor 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 conditionby measuring the voltage, current and power factor of the testsignal. 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
