China High Quality High Voltage Meter Supplier – GDBT-1000kVA Transformer Test Bench – HV Hipot Detail:

General Information

Test Object:
22.9kV Single Phase transformers and special transformers, load voltage and current: AC 0-650V/78A, AC 0-1200V/29A, AC 0-2400V/14.6A
The impedance of tested transformer is within 7%, HV side is 23kV, 11kV, 6kV. LV side is 0.05kV-2.4kV.

This test bench can conduct below test:
1. No-load test including no-load loss, the percent of no-load current to rated current.
2. Load test including load loss, impedance voltage percentage, automatic temperature conversion and load loss test under 30% or above full current.
3. Induced voltage test.

Features

● 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 (75℃, 100℃, 120℃, 145℃) 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.
