HZYA-2Z-I Handheld Transformer On-Load Switch Tap-Changer Tester

Overview

On-load tap changer is the only moving part connected with the transformer circuit, so the detection of on-load tap changer should be attracted more and more attention. In <>, it is required to check the action sequence of on-load tap changer and measure the switching time. The instrument is mainly used for measuring the transformer on-load tap switch transition waveform, transition time, each instant transition resistance value, three-phase synchronization, etc.

The HZYA-2Z-I instrument is high intelligent degree.It is easy to operate with all English menu prompts. The instrument is small in size, light in weight and strong in anti-interference ability, which greatly reduces the labor intensity of the field staff. It is an ideal instrument for ensuring safe production and improving product quality in power supply units and transformer manufacturing industry.
