Transformer Short Circuit Impedance Tester VATST800
Transformer Short Circuit Impedance Tester

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 VATST800 is used to measure short circuit impedance and other associated parameters of power transformers according to standard IEC60076-5-2006.
