IEC Standard China Automatic Transformer Test Bench Transformer
Testing System Load Loss No Load Current High Voltage TesterGeneral
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.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 testingTransformer winding resistance testingTransformer
turns ratio testingTransformer load/no-load current & loss
testingTransformer capacitance & tan delta testing Transformer
short circuit impedance & load loss testingTransformer power
frequency withstand voltage testingTransformer induced AC withstand
voltage testing (including 110kV transformer partial discharge
testing)Impulse voltage testing (including full wave, chopping wave
testing)Type tests:Temperature rising testingSpecial
tests:Zero-sequence impedance testingNo load current harmonic
