1、 Overview

The comprehensive test bench complies with relevant national standards such as GB/T4776, GB/T5169, GB/4285-1993, etc.

This test bench is mainly used to test the no-load characteristics of the iron cores of power transformers and distribution transformers. The measuring part of the device is controlled by a high-end microcontroller, and the digital display and no-load test data are synchronously sampled by the microcontroller, avoiding the errors caused by manual calculation of voltage, ammeter, and power meter readings in traditional testing methods.
