On load tap changer tester I-1A, required for power qualification

​

1、 Product Overview

Please read the instruction manual carefully before testing;

To ensure accurate testing, please demagnetize the power transformer or conduct a DC resistance test before using this instrument.

Transformer on loadtap-offswitchfeatureA tester is a comprehensive measuring instrument used to measure and analyze the electrical performance indicators of power transformers and special transformers on load tap changers in power systems. It adopts computer control and can realize the measurement of on load tap changers through specially designed measurement circuitstransition time、Transition waveform、Transition resistance、Three phase synchronicityThe measurement of parameters such as, can be directly measured by the tap changer leads according to the needs and site conditions, or by the transformer three-phase bushing and neutral point direct wiring measurement.

This instrument has functions such as analyzing, storing, and printing the measured data. Solved the problem of outdated measurement methods and lack of testing methods for on load tap changers in current power transformers. It can timely diagnose potential faults in on load tap changers during preventive testing of power equipment and transformer maintenance, which is of great significance for improving the reliability of power system operation.

The instrument has a high degree of intelligence, with all Chinese menu prompts and simple operation. The instrument has a small volume, light weight, and strong resistance, 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.
