Portable GDBR-P Transformer Capacitance and Load No Load Tester

General Information

GDBR-P Transformer Load, No-load and Capacity Tester is a multi-function measuring instrument, which is equivalent to two kinds of test instruments: Transformer Capacity Tester + Transformer Characteristic Parameter Tester. It can accurately measure a series of power frequency parameters such as capacity, type, no-load current, no-load loss, short-circuit (load) loss, and impedance voltage of various transformers.

It has many advantages such as small size, light weight, high measurement accuracy, good stability and simple operation. It can completely replace the method of measuring transformer loss and capacity by using multi-meter method in the past. The wiring is simpler, the test and recording are more convenient, so that the work efficiency has been greatly improved.


1. Measure transformer No-load current, No-load loss, short circuit voltage, short circuit loss and capacity.
Three meters testing methods.
2. When making three phase transformer No-load, load test, the instrument will judge if the wiring is correct automatically, and shows three phase voltage, current vector diagram.
3. Finish load test under 1600kVA below distribution transformer full current for single machine. Finish 2500kVA below distribution transformer load test under 1/3 rated current (Under 1/3 rated current, the instrument can be converted to load loss parameters under rated current. )
4. All test results are corrected automatically. The instrument automatic correction as follows, waveform correction, temperature correction, Non rated voltage correction and non rated current correction. The test results are more accurate.
5. 320*240 high brightness LCD screen, with brightness adjustment. Touch buttons make the operation more convenient.
6. Real-time clock, recording test date automatically, suitable for storage and management of test results.
7. Built-in panel-type thermal printer, fast print test results.
8. Power down store and browse data (test object set, measurement results, test time) functions. Store up to 500groups test results, data transmission online to PC.
9. Allows extended range measurement for external voltage transformer and current transformer. Measure test object of any parameters.
