Transber Testers - ClearTest

The ClearTest^® Transber Tester provides quick and easy tests of de-energized power distribution system transbers. It is a handheld device with a single pushbutton that provides a b indication of open circuits, short circuits, including shorted turns or shorted windings and confirmation that the test results are OK.

The ClearTest is a compleby new design that briefly energizes the transber and takes a snapshot of the transber condition by measuring the voltage, current and power factor of the test signal.

The ClearTest finds transber defects that include:

? A single shorted turn in the primary or secondary side of a transber
? 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 transber ratios resulting from shorted turns

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