Extended Handling May Be Required
  • Quickly tests deenergized power distribution transformers
  • Briefly energizes the transformer and takes a snapshot of the condition by measuring the voltage, current and power factor of the test signal
  • Tests overhead, pad-mount and distribution transformers
  • Audible alarm confirms successful test
  • Improve SAIDI statistics by quickly testing and getting the transformer back in service
Overview
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

About Manufacturer
Greenlee

Founded in 1862, Greenlee Tools got its start as a toolmaker when two brothers needed to manufacture their invention (a special drill surrounded by chisels). With the success of this effort, the Greenlee brothers quickly took on making other woodworking tools and other machinery including a machine that laid track for the railroad. In the mid-80s and beyond, Greenlee added on other toolmakers and diversified the kinds of tools they make and now Greenlee manufactures tools used by tradesmen in all vocations from communications to hydraulic pumps, plumbing, telecom, test equipment and many more. Greenlee is widely recognized as an industry leader for quality hand and industrial tools.
