GDHG-206 CT/PT On-site Calibrator

GDHG-206 CT/PT On-site Calibrator

General introduction

GDHG-206 CT/PT On-site Calibrator is designed for analyzing current transformers and voltage transformers of ratio error, angle error, ratio error/angle error of 1%-200% current. It can directly measure turns ratio and polarity, actual secondary burden of CT/PT.

The model uses DC and AC power supply with high precision and automatic linear adjustment. High speed and reliable digital processing module is also adopted.
