【Features】
Current transformer(CT)testing in accordance with the current ratio error test of the international standard IEC60044-1 is available. Voltage transformer(VT)testing in acordance with the voltage error test of the international standard IE60044-2 is available. The ratio error,phase displacement,test voltagel,test current,and test frequency can be measured. The ratio error is indicated in units of either %or RCF(Ratio Correction Factor),and the phase displacement is indicated in units of either minutes or centi-radians;thus it is appropriate for ANSI/IEEE tests. USB interface is a standard fixture. Errors for up to 10 measurement standards can be registered,and measurements are made with errors being automatically corrected. Different-ratio testinig is availble by incorporating an optional CT or VT different-ratio adapter. The internal burden of this equipment is as small as 0.1 VA introducing a built-in internal burden compensation circuit(patent pending). |
