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％ and10％ 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.
Precautions
1、In order to ensure the safety of persons and equipment, please carefully read the operation manual before using the tester.
2、The tester shall be reliably grounded when used, or persons or equipment may be damaged.
3、Touching the connection terminals in the test is strictly forbidden.
4、The tested CT must be in offline state, or the normal application may be affected or the test result may be incorrect.
5、The tester shall be operated by professional technicians.
6、Individually opening the equipment may lead to permanent damage.
