GDBR-P Transformer Power Analyzer/Transformer Capacity Tester/Transformer Impedance Voltage Tester
Product Description
GDBR-P is mainly used to test capacity, No-load current, No-load loss, short circuit(load) loss, impedance voltage for transformers.
Features
Accurately measure the capacity of various distribution transformers, which is convenient and accurate.
Measure transformer No-load current, No-load loss, short circuit voltage, short circuit loss and capacity.
Auto range switching, wide allowable measuring voltage and current range and simple wiring.
Three meters testing methods.
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.
Finish load test under 1000kVA below distribution transformer full current for single machine. Finish 3150kVA 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.)
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 to make the test results more accurate.
320*240 high brightness LCD screen, with brightness adjustment. Touch buttons make the operation more convenient.
The instrument can preset 40 sets of test sample parameters by the user, and these parameters can be deleted and added at any time as needed, which is very convenient to use.
Real-time clock, recording test date automatically, suitable for storage and management of test results.
Built-in panel-type thermal printer, fast print test results.
Power down store and browse data (test object set, measurement results, test time) functions. Store up to 500 groups test results, data transmission online to PC.
Allows extended range measurement for external voltage transformer and current transformer. Measure test object of any parameters.
