Learn how to test a transformer: insulation resistance, TTR, winding resistance, polarity, continuity, and dielectric checks.

Short-circuit currents represent a tremendous amount of destructive energy, which can be released through electrical systems under fault conditions. Baseline short-circuit studies should be performed ...

Delays in short-circuit protection triggers require careful selection of the magnetics and overcurrent threshold values to prevent component stress. In any off-line flyback converter design, it is ...

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 ...
