Product Description

Product Description

For a power system,the transformer is a core component,and the long-term and reliableoperation of the transformer is crucial for the stability and reliability of the entire system.
This instrument is designed with fully intelligent one-touch testing functions for DCresistance andturns ratio testing.Based on the set testing parameters,it intelligently identifies thecurrent tapposition of the transformer, automatically tests and saves the turns ratio and DC resistancedata for that tap position.
