Product Description

Electronic Transformer Calibrator

General Information:

The high-voltage electric energy metering devices of power plants and substations, as well as the electric energy metering devices of many users, are related to the interests of power generation, transmission, power supply and users. To ensure the accuracy of the measurement, the inspection must be carried out in accordance with the "Inspection Regulations for Electric Energy Metering Devices" and "Technical Management Regulations for Electric Energy Metering Devices".

EPTR-60 transformer field calibrator is based on high-end testing technology and large-scale electronic circuit design. It solves the problem of large work intensity and cumbersome operation of field verification transformers. At the same time, the product has reliable performance and powerful functions.
