We carry out electrical tests on transformers, autotransformers, reactors, voltage and current transformers.





Tests are performed with connection to de-energized equipment, accurately measuring turns ratio, excitation, winding resistance, polarity and phase error, simultaneously displaying polarity and excitation current.



We used the test method according to IEEE Standard C57.12-90-2006, checking for turns / connections / open circuit breakers, short circuits (excess excitation current) and reversed polarity. Measurements are fast and accurate.
