Singe Phase or Three-phase Transformer Group Vector Measurement Equipment for Ratio Error Test

Introduction

The voltage ratio measurement for three or singe phase transformer

The group vector measurement for three phase transformer.

The polarity measurement for single phase transformer or CT/PT

Voltage ratio error calculation

Current transformer ratio measurement

Excitation current measurement in ratio testing

Reproduction the AC test voltage from power source to reduce the effects of bad power source

Save the test results in the memory internal the tester

Print the test results by micro printer

Reverse connection detect unit to prevent the high voltage injected to operator

Over current protection unit integrated in software and hardware

Upload the test results to PC by RS232 and make word report by software

Benefits

• The test power supply is generated by the internal power amplifier of the tester, and the waveform distortion rate is less than 0.5% and is not affected by the quality of power supply.
• Automatic voltage regulation, with automatic protection functions such as transformer reverse connection, over-current, etc., to avoid damage to the instrument due to incorrect operation.

• It can be used for power transformer, CT and PT ratio detection.
• Convenient standard transformation ratio setting template, don’t need to manually calculate the standard transformation ratio value.

• The TTR is very light, only 20KG. It’s easy to carry. It’s suitable for field test.
