Handheld transformer on load switch tester

Instrument Overview
The on load tap changer of a transformer is an important moving component connected to the transformer circuit, therefore, 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.
Created by Yangzhou Topu Electric Technology Co., LtdHandheld transformer on load switch testerMainly used to measure the transition waveform, transition time, instantaneous transition resistance values, three-phase synchronicity and other parameters of on load tap changers in transformers. The instrument has a high degree of intelligence, using a color touch LCD screen for operation, Chinese menu prompts, and simple operation. The instrument has a small size, light weight, handheld operation, and anti-interference abilityStrong strength greatly reduces the labor intensity of on-site workers, making it an ideal instrument for power generation units and transformer manufacturing industries to ensure safe production and improve product quality.

Features
1. This instrument uses a 7-inch color touch LCD screen display for easy on-site operation.
2. The instrument has a high output current, is lightweight, and is designed to be handheld and portable.
3. Test YN, Y, and △ transformers, and display resistance values directly without conversion.
4. Can be measured with or without windings.
5. The waveform display automatically adjusts the resistance and time value amplitude based on the sampled values.
6. This device has a complete protection circuit and strong reliability.
7. ThisHandheld transformer on load switch testerInternally, 500 sets of data can be automatically saved.
