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

So there I was with this mystery transformer on which someone put a label showing three different speaker load impedance, but with no indication of what the intended primary winding impedance happens ...

The EZCT-S2 from Vanguard Instruments is a second-generation, microprocessor-based, current transformer set. The EZCT-S2 will perform the current transformer saturation test and the CT (current ...

Air conditioning transformers are essential components for proper system function. They power the thermostat and regulate the current sent to it. That’s essential because a current that’s too high ...
