IEC Transformer Test Bench Transformer Testing System

Product Description

IEC Transformer Test Bench Transformer Testing System 

General Information:
EPBZ series Transformer Test Bench is applied for ex-work and maintenance detecting on various transformers. It's widely used in the fields of power supply and distribution, power transformer manufacturer, transformer maintenance center, industry and mining enterprises.

Features

· Applied for different voltage degree transformers, reactors and HV switchgears. 

· Fully PLC controlling and measurement, integrated primary wire connection circuit displaying, measuring, control tracing, analysis processing, report storing, printing and protecting into the testing system.

· All the test data calculation was operated by IPC, the test results and measuring data are displayed in screen directly which highly improved the precision and efficiency. 

· The test system could be customized to bench type, microcomputer type or any at user's option to be suitable for your test site.

· All test results are corrected according to the requirement of IEC60076 or ANSI C57.
