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

Voltage transformers (VT) are used in electrical grids for metering and/or protection purposes. The high requirements regarding their precision demand a calibration ...

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

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 ...

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 ...
