China IEC 60076 Compelte Transformer Test 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.
FeaturesApplied 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.
