Supply of JYR transformer on load tap changer parameter tester

Overview

The on load tap changer is a moving component connected to the transformer circuit, so the detection of on load tap changers is becoming increasingly important. In the "Regulations for Handover and Preventive Testing of Power Equipment", it is required to check the sequence of action of on load tap changers, measure switching time, etc. To this end, our company has successfully developed a transformer on load tap changer parameter testing instrument, which is mainly used to measure the transition waveform, transition time, instantaneous transition resistance value, three-phase synchronicity, etc. of the transformer on load tap changer.

The instrument has a high degree of intelligence, with all Chinese menu prompts and simple operation. The instrument has a small size, light weight, and strong anti-interference ability, greatly reducing the labor intensity of on-site workers. It is an ideal instrument for power generation and supply units, transformer manufacturing industry to ensure safety production and improve product quality.

Testing and operation methods

Precautions for operation:

Before use, the grounding terminal of the instrument must be properly grounded.

During the testing process, it is not allowed to dismantle the testing line.

When testing with windings, the non test end of the transformer should be grounded in a three-phase short circuit.

If you choose to store data toUDisk or queryUPlease store the data in the diskUDisk insertion“UDisk interface ", and in the direction ofUIt is not allowed to unplug during the process of storing or querying data on the diskUPlate.
