EPBZ series
Automatic Transformer Test Bench
General Information:
EPBZ series Transformer Test System 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.
Test Items:
Routine tests:
- ♦ Transformer oil testing (including acidity, dewpoint, flashpoint, breakdown, capacitance &tan delta, dissolved gas analysis)
- ♦ Transformer insulation resistance testing
