UHV-321 Transformer Load And No-load Losses Tester-Catalog

Product catalog summary

Product Introduction
The UHV-321 Transformer Capacity Load No-load Tester is designed to measure transformer load current, load loss, short-circuit voltage, and short-circuit (load) losses. It requires a three-phase regulator for transformer load no-load tests.

Product Features
The tester can perform three-phase transformer no-load and load tests, automatically verifying correct wiring and displaying voltage and current vector maps. It supports full load current experiments for 100KVA transformers and tests for 250KVA transformers at one-third rated current. The device automatically corrects test results for waveform, temperature, voltage, and current discrepancies. It features a 320x240 LCD display with adjustable brightness, a real-time clock for recording test data, and a thermal printer for quick result printing. It can store up to 500 test results and allows data transfer to a computer.
