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.

Transformer Tester Features

·         Finds internal transformer defects before energizing

·         One tester for all transformer types

·         Test the primary and secondary sides of de-energized transformers without disconnecting

·         Tests all connections from transformer to meter

·         Improve SAIDI statistics by quickly testing and getting the transformer back in service

·         Prevents line workers from installing a fuse on a shorted transformer

·         Quickly verifies the secondary connections are not shorted

·         Compact, lightweight and easy-to-use

·         Powered by two 9V field replaceable lithium or alkaline batteries

·         Audible alarm confirms successful test

·         Built-in self test

·         A magnet is included to hold the ClearTest in place while testing
