Scope of application
It is suitable for the test of power system CT volt-ampere characteristics, PT volt-ampere characteristics, CT transformation ratio polarity, PT transformation ratio polarity, and transformer secondary load.
Performance characteristics
(1) Combine CT (PT) volt-ampere, CT (PT) transformation ratio polarity, inflection point voltage and current, secondary load, channel, fixed value, 10% (5%) error curve, rated no-load loss, and multiple Functional device
(2) Multi-winding (multi-channel) synchronous test, 6 sets of CT secondary winding transformation ratio tests are completed at one time; transformation ratio and polarity tests are completed at the same time;
(3) Arbitrary setting of characteristic value of volt-ampere test;
(4) Real-time test curve and data display, intelligent misoperation prompt;
(5) The test output voltage is isolated from the input power supply with multiple protections (protection against overload, short circuit, software, etc.).
