Transformer Short Circuit Impedance Tester

Model: TST800

The winding mechanical deformation of transformers can occur during transportation, installation, or high current events in operation. Such changes can be detected by comparing before and after short circuit impedance measurement values.

Transformer Short Circuit Impedance Tester TST800 is used to measure short circuit impedance and other associated parameters of power transformers according to standard IEC60076-5-2006.

Main Features

1) Able to measure the short circuit impedance of transformers without external voltage regulator

2) Useful in detecting and diagnosing winding deformation

3) Able to perform short circuit impedance test in single or three-phase transformers

4) Auto or manual test mode selectable

5) Able to measure zero sequence impedance and inductance

6) Has output current limiting function for any impedance sample test.

7) The test results can be save into instrument or printed out via built-in thermal printer, also can be exported via USB port.
