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

Designing flyback transformers for switch-mode power supplies involves many calculations. A spreadsheet can make short work of this otherwise-tedious task. When you develop flyback power supplies, ...

In a large solar installation, high harmonics from inverters can destroy transformers primarily by causing excessive heat ...

The electrical configuration of the delta-wye transformer makes it the most popular transformer connection in the world. When it comes to making proper transformer connections, more industry ...

Transformers for power applications often are limited in size by an acceptable temperature rise. An acceptable temperature rise of a transformer is usually George G. Orenchak, General Manager, TSC ...

So you have an old tube-type transmitter as a backup. It ran perfectly when you last turned it on two years ago to substitute for your then-ailing solid-state main transmitter. Now you need it again.

Cooper Power Systems has designed its full-featured differential relay, the iXP-420, to provide comprehensive two-winding transformer protection, and monitoring and control. The iXP-420 incorporates ...

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 ...
