Product Introduction
CT/PT TESTER 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, self-equipped minitype printer supporting field printing; supporting to use USB flash disk to dump data, with simple and convenient operation.
