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
