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 ...

Transformers are very reliable devices and can provide service for a long time if regularly maintained and serviced. They’re also the single most costly item in any substation. To protect against ...

The low-power (milliwatt) flyback transformer used in a switched-mode power supply (SMPS) needs to be designed with a gap in the magnetic path for maximum power delivery over temperature. Transformers ...

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 ...

In the absence of expensive test equipment, the circuit in Figure 1 offers a simple and rapid alternative method of measuring inductance. Its applications include verifying that an inductor’s value ...
