Ⅰ: Brief introduction about the CT/PT ANALYZER:
CT/PT ANALYZER is mainly used for field testing of P class CT and PT. The test items mainly include excitation characteristic, transformation ratio, polarity, Degauss, 5% and 10% error curves, secondary circuit check, withstand test of power frequency alternating current and secondary load. Adopt LCD, built-in printer supporting field printing; supporting to use USB flash disk to transfer data, with simple and convenient operation.
Designed for automatic testing of protection and metrology CT / PT, suitable for laboratory and field testing.
