The GF1060M micro current transformer test equipment is developed by GFUVE GROUP, which integrates a high precision 0.05% current source output from 0 to 120A and A calibration device that integrates current transformer calibration, mainly used for automatic test equipment of miniature current transformers and electronic current transformers in digital substations or miniature current transformer factory. The built-in current source is a new generation of high-precision standard power source based on 1.2G MAC DSP, large-scale FPGA, high-speed and high-precision DA, and high fidelity power amplifier. The built-in current transformer calibrator also adopts a dual CPU architecture, with powerful functions. It greatly expands the bandwidth and improves measurement accuracy with a 24 bit AD chip and 512 times oversampling technology. GF1060M has an accuracy of 0.05 class and can calibrate current transformers below 0.2S level.
