High Accuracy Test Equipment Device Transformer on-load Lap Changer Tester
Product 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. |
FEATURES
1. The instrument has large output current and light weight; 2. Test YN, Y, D transformers, and the resistance value can be displayed directly without conversion; 3. It can be measured with and without windings; 4. Waveform display automatically adjusts the amplitude of resistance and time value according to the sampled value. 5. It has a complete protection circuit and strong reliability; 6. Large 7-inch LCD display, convenient for on-site operation; 7. 500 sets of data can be automatically saved internally. 8. The instrument has Bluetooth communication. |
