Product Introduction

    TPFKC-B Transformer On-load Tap Changer Tester is a comprehensive testing device used to measure and analyze the electrical performance indicators of on-load tap changers in power transformers and special transformers in power systems.Through a specially designed measurement circuit, this instrument can measure parameters such as transition time, transition waveform, transition resistance, and three-phase synchronization of the on-load tap changer. Users can directly measure from the tap changer leads or connect directly from the transformer three-phase bushings and neutral point according to needs and on-site conditions.

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 It solves the problem of outdated measurement methods and lack of specialized testing means for on-load tap changers in power transformers.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

    This instrument has a high degree of intelligence, with all operations guided by Chinese menu prompts, making it simple to operate. The instrument is small in size, light in weight, and has strong anti-interference capability, greatly reducing the labor intensity of on-site workers. It is an ideal instrument for power generation and supply units and transformer manufacturing industries to ensure safe production and improve product quality.

Functional Features

1. The instrument outputs an open-circuit voltage of 30V, and can test transition resistance up to 30Ω at a current of 1A, automatically calculating the transition resistance value and transition time value.

2. This transformer on-load tap changer tester has a large output current and is light in weight.

3. The instrument has a comprehensive protection circuit and high reliability.

4. The instrument uses a large LCD screen for easy on-site operation.

5. The instrument has storage function and can analyze data waveforms.
