Product Description

Transformer Test Bench Double Voltage Double Frequency Test Equipment (DVDF / OVIT Test)


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.
