General introduction
GDBT-1000kVA is mainly to make no-load, load and induction voltage test for 23kV single phase transformers.
The measurement part is controlled by single chip. Digital display, no-load and short circuit test data will be sampling by single chip at the same time.
Manual record test data and save in the database.
The data of No-load test can be corrected by waveform and rated voltage automatically.
The data of Load test can be corrected by temperature (75ºC, 100ºC, 120ºC, 145ºC) and rated current.
In No-load test, LV side voltage can be monitored.
In Load test, HV side current can be monitored.
All test functions and test process can be selected and controlled by buttons of front panel.
All test results are corrected according to the requirement of GB1094, IEC60076 or ANSI C57.
Test procedure can be proceed by PC software.
All data can be stored and printed.
With zero protection, over-current protection and over-voltage protection functions.
CT/PT range switch automatically.
The test bench will fully control to the whole loop circuit and monitor the measurement.
Safety alarm system.
