HZB1101 Transformer Ratio Tester

HZB1101 Transformer Ratio Tester

During the production of semi-finished and finished power transformers, before new transformers are put into operation, and in accordance with the preventive test regulations of the State Grid, regular turns ratio or voltage ratio testing is required. Traditional ratio bridges are cumbersome to operate, provide non-intuitive readings, require additional calculations, and only give the ratio of a single phase.

Our Transformer Turns Ratio Tester overcomes all these shortcomings. It features a large high‑resolution LCD screen, is easy to use in the field, and provides a Chinese menu prompt (localized versions available). Operation is simple and intuitive – the three‑phase ratio test is completed in one go with fast speed and high accuracy.

Key Features
  • Three-phase sine inverter power supply, auto voltage adjustment, soft start & soft stop design
  • All-in-one test: ratio, vector group and polarity for single-phase / three-phase transformer, PT and Z-type transformer
  • Support intelligent blind test without high/low voltage connection information
  • Built-in CT ratio & polarity test function; phase angle difference test for single-phase mode
  • Max 197 tap gears testable, ultra-wide measuring range up to 10000
  • Dual safety protection: HV-LV reverse connection protection, output short-circuit protection
  • 500 sets local data storage + U-disk export, Word format data for direct edit & print
  • Off-line clock calendar, silent thermal printer, portable lightweight body
