China High Precision 5000kVA 11kv33kv Automatical Transformer Testing Bench Distribution Transformer Test System Power Transformer Test Bed
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.
