Current Voltage Transformer CT PT Volt-Ampere Excitation Curve Characteristic Tester
This device is designed to meet the testing requirements for various Current Transformers (CT) including excitation characteristics transformation ratio,polarity,secondary winding resistance,secondary load,ratio error,and phase angleerror.Additionally,it can be used for testing the excitation characteristics transformation ratio,polarity,and secondary winding resistance of various Potential Transformers(PT)electromagnetic units.
- Comprehensive functionality.
- Automatically provides knee point voltage/current,10%(5%)error curve,Accuracy Limit Factor(ALF),Instrument Security Factor(FS),secondary timeconstant (Ts),remanence. coefficient(Kr),and otherCT/PT parameters.
- The tests comply with various transformer standards.
- Utilizing advanced low-frequency testing principles,it can handle CTtesting with kneepoints up to 30kV.
- One-click completionof CT resistance,excitation,transformation ratio,and polarity tests using the samewiring method.
- The device is easy to carry.
