Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

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.

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

If the reliability of the public electricity supply is to be maintained in the future, routine diagnostic testing of transformers by the power utilities is no longer optional – it’s a necessity, ...

In switched-mode power supplies (SMPS), magnetic components, namely inductors and transformers, play critical roles. Much of the SMPS design process relies on component specifications and simulation ...

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 ...

To investigate the electrical realm of high-frequency and high-voltage, Tesla invented an apparatus that pushed the limits of electrical understanding. None of the circuit's typical components were ...
