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 ...

Over on his YouTube channel our hacker [Jerry Walker] repairs a Tektronix 577 curve tracer. A curve tracer is a piece of equipment which plots I-V (current vs voltage) curves, among other things. This ...

WHEN an electric generator is accidentally short-circuited, huge currents are developed and unless the ‘pcircuit-breakers’ act promptly, serious damage may be done to the generator and there is a risk ...

I’m sure many readers would question why anyone would want to perform a relatively expensive insulation power factor test on an inexpensive transformer. Typically, if any testing is done, it will be ...

Planar transformers and inductors for high-frequency converters differ radically from conventional magnetics in that they do not use magnet wire. Instead, windings are copper-foil lead frames or flat ...
