Accuracy & excitation tests for instrument transformers
Comprehensive analysis of current and voltage transformers — ratio, polarity, excitation (knee-point), winding resistance and burden — for metering accuracy verification and protection-class assessment.
Real models from our current catalogue. Voltage, current and functions can be customised to your test object — send us your specification.
