Features
1. CT test
Excitation (VA) characteristic
Ratio test
Polarity Test
Secondary winding resistance test
Secondary burden test
Ratio error
Phase error test
2. PT test (electro-magnetic type)
Excitation (VA) characteristic
Ratio Test
Polarity test
Secondary winding resistance test
Secondary burden test
Phase error test
3. Automatically provide CT&PT parameters including knee point voltage/current, 10% & 5% error curve,
ALF (accuracy limit factor), FS (Instrument security factor), secondary time constant (Ts), Remanence
coefficient (Kr), saturated inductance, and etc…
4. Adopt low frequency method test principle and can perform the test of CT with knee point up to 30KV
5. CT admittance test
6. Adopt popular square wave method and can get more perfect excitation curve
7. Big storage space can ensure saving of more than 100000 test data.
8. Directly generate Excel report after finishing test, also can directly printer
9. Simple operation: one-key finish CT winding resistance test & excitation test & ratio test & polarity test;
except burden test, other tests all adopt same wiring
