Product Description

Fully-automatic Transformer Load And No-Load Test Equipment 

Introduction

GDBR-P transformer no-load tester can measure the AC voltage effective value, voltage average value, effective value, active power, power factor and frequency of three-phase power transformers. The measurement accuracy is 0.1, intelligent and professional design 3. Suitable for testing of no-load, load, induction and other tests of power transformers.

 

Features

• Measure transformer no-load current, no-load loss, short-circuit voltage, short-circuit loss and capacity.
• Three meter test method.
• When the three-phase transformer is under no load and load test, the instrument will automatically determine whether the wiring is correct and display the three-phase voltage and current vector diagram.
• The load test is completed at 1600kVA below the full current of a single distribution transformer. 2500kVA lower than the distribution transformer load test at 1/3 rated current (At 1/3 rated current, the instrument can be converted to load loss parameters at rated current.)
• All test results are automatically corrected. The instrument automatically calibrates as follows, waveform correction, temperature correction, non-rated voltage correction and non-rated current correction. The test results are more accurate.
• 320 * 240 high-brightness LCD display with brightness adjustment function. The touch button makes the operation more convenient.
• Real-time clock, automatic recording of test date, suitable for storing and managing test results.
• Built-in panel-type thermal printer to quickly print test results.
• Turn off the function of storing and browsing data (test object set, measurement result, test time). Store up to 500 test results and transfer data to PC online.
• Allows extended range of external voltage and current transformer measurements. Test object that measures any parameter.
