UHV-321 Transformer Capacity Load No-load Tester

Product Introduction

This product is specifically designed for capacity measurement, no-load loss testing, and short-circuit loss analysis of distribution power transformers. It also features harmonic analysis functionality, enabling effective assessment of on-site power quality. When testing three-phase transformers, the device automatically verifies wiring correctness and displays a three-phase current-voltage vector diagram. Furthermore, it incorporates multiple correction mechanisms—such as waveform, temperature, non-rated voltage/current, and calibration corrections—ensuring highly accurate and reliable test results.

Common Troubleshooting

Boot no display: first off, open the socket on the back panel AC 220V fuse box, check the fuse box, you can replace insurance. The screen suddenly black screen: press the reset button, to start measurement. Measurement and computation results are not correct: Check the external wiring, whether by manual operation, whether bad or take the wrong line; relevant parameter is incorrect. Measuring voltage and current display to zero the normal, check whether the current file fuse blown
