Portable Precision Current Transformer Testing CT PT Analyzer
GF1061 portable CT PT analyzer is mainly used for field or lab testing, it can finish the measurements (M) and protection (P) class CT, PT and TYP class CT. Adopt 7 inch touch TFT LCD, self-equipped mini type printer supporting field printing; supporting to use USB flash disk to download data or RS232 port to PC control. This model GF1061 CT PT Analyzer is the most complete and easy-to-use testing system for protection and metering CTs according to IEEE C57.13 and IEC60044 & IEC61869 standards. It can test current transformer phase error, ratio error, polarity, winding DC resistance, excitation curve, composite error and degauss etc, and also test voltage transformer phase error, ratio error, polarity, winding resistance, degauss etc. This test data can be download word test report by PC management software.
