Sumpner’s Test Using Two Single Phase Transformers

SALIENT FEATURES :
Sumpner’s Test using Two Single phase Transformers, is a versatile and self contained trainer kit
useful for conducting Sumpner’s Test experiment using two single phase transformers. The trainer kit is
useful for the conducting Sumpner’s test experiment and polarity phenomenon. The unit is housed in an
elegant metal cabinet with a well spread intelligently deigned layout on the front panel. It is strongly
supported by a comprehensive instruction manual complete with theory operating details and procedure.
