Learn how to test a transformer: insulation resistance, TTR, winding resistance, polarity, continuity, and dielectric checks.

This test set uniquely combines winding resistance measurement, transformer turns ratio, tap changer dynamic resistance, core demagnetization, transformer type detection, magnetic balance, short ...

Omicron has introduced a way to test current transformers at all lifecycle stages by using a testing method called "the modeling concept". The "traditional" way of testing a current transformer is to ...

The use of a copper winding as a temperature sensor for transformer windings is not new. But the circuit presented here goes further. It can make the measurement in-circuit and in real time. The use ...

Alpha-Core introduces the Model HBC-2 turns counter, a precision instrument that accurately counts the number of turns of magnet wire in toroidal and other types of core transformers. The HBC-2 also ...
