China Transformer Winding Resistance DC Resistance Meter Transformer Ohm Meter, Find details about China Testing Machine, Testing Equipment from Transformer Winding Resistance DC Resistance Meter Transformer Ohm Meter
DC resistance test of transformer windings is an essential test item after transformer handover, overhaul and change of tap switch.
It is an innovative product, built-in large capacity lithium battery, the instrument and the test line adopt machine line integrated design, the product volume is small, easy to carry. The products are not only suitable for the measurement of inductive test products such as transformer, mutual inductor and reactor, but also suitable for the measurement of resistive test products such as copper bar, conductor and switch contact.
