Portable Precision Current Transformer Testing CT PT Analyzer

ct 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 dump data. The CT PT Analyzer is the most complete and easy-to-use testing system for protection and metering CTs according to IEEE and IEC standards.
