| Instrument Transformer Performance Parameter Tester |
|
Dary Electric recommends Product Introduction The Instrument Transformer Comprehensive Characteristic Tester is capable of testing excitation characteristics, transformation ratio, polarity, DC resistance of secondary winding, and AC load of CT secondary circuit for current transformers and voltage transformers. |
The Instrument Transformer Comprehensive Characteristic Tester uses frequency conversion technology to test the excitation characteristics of current transformers with knee point voltage below 30KV.
★ Test the transformation ratio and polarity of current transformers (including CTs in transformer bushings).
★ Test the DC resistance of secondary winding and circuit load of current transformers.
★ Test the excitation characteristics, transformation ratio polarity, and DC resistance of secondary winding of voltage transformers.
★ Plot excitation curves and calculate knee point voltage/current, plot 5% and 10% error curves.
★ Measure ratio error and phase error. Determine remanence coefficient, excitation inductance, secondary time constant, transient area coefficient, peak value instantaneous error, accuracy limit factor, and instrument security factor.
★ Automatic wiring detection with alarm for wiring errors. Data can be transferred to PC via USB drive to generate Word format reports.
