Xtester-ZKSII-Transformer on-load tap changer tester,on-load tap changing tester,OLCT Tester
Overview
The on-load tap-changer is the only moving part connected to the transformer circuit. Therefore, the detection of on-load tap-changers has attracted more and more attention. In the "Power Equipment Handover and Preventive Test Regulations", it is required to check the action sequence of the on-load tap-changer and measure the switching time. This instrument is mainly used to measure the transition waveform, transition time, transient resistance value of the on-load tap changer of transformer, and three-phase consistency.
The instrument has a high degree of intelligence, all Chinese menu prompts, and simple operation. The instrument is small in size, light in weight, and strong in anti-interference ability, which greatly reduces the labor intensity of on-site workers. It is an ideal instrument for power generation and power supply units and transformer manufacturing industries to ensure safe production and improve product quality. |
