GF106 CT test set (CT Analyzer) is a current transformer test equipment specially designed for current transformer characteristic test and with additional PT test functions for reference test. GF106 CT test equipment is mainly used for field testing, it can finish the measurements (M) and protection (P) class CT, PT and TYP class CT. GF106 CT test equipment can also guessed CT ratio test equipment because of the additional functions including ratio and angle differential tests (the measurement points in the IEC60044 & IEC61869 standard), FS and inductance, steady-state parameters, peak error and transient parameters, etc. Adopt 5.6 inch LCD, self-equipped mini type printer supporting field printing; supporting to use USB flash disk to download data, with simple and convenient operation.
