In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.

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 ...

Those readers who have experimented with winding their own inductors will know that it’s not an easy task, and when those inductors are handling high voltages it can be especially tricky to maintain ...

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

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 ...

Beckwith Electric's Transformer Protection System M-3311A provides protection, control, monitoring and user interface functions for two, three or four-winding transformers Beckwith Electric's ...

Like all of the electrical distribution equipment serving critical systems, transformers are a key component. That's why it's crucial to evaluate your decision from every angle before choosing a unit.

The flyback design is a switched-mode power supply (SMPS) that’s been used for 70+ years and still going strong. This supply—also called a power converter—has two distinct operating phases, with power ...
