Description
Overview
On-load tap changer is the only moving part connected with transformer circuit, so the detection of on-load tap changer attracts more and more attention. In the Regulation of Power Equipment Handover and Preventive Test, it is required to check the action sequence of on-load tap changer and measure the switching time. The instrument is mainly used to measure the transient waveform, transient time, transient resistance value at each moment, three-phase synchronization and so on of transformer on-load tap changer.
The instrument has a high degree of intelligence, all English menu prompts and simple operation. The instrument has the advantages of small volume, light weight and strong anti-interference ability, which greatly reduces the labor intensity of field 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 Characteristics
The instrument has large output current and light weight;
Test Yn, Y and D transformers, and the resistance value is displayed directly without conversion;
Can be measured with or without winding;
Waveform display automatically adjusts the amplitude of resistance and time value according to the sampling value.
With perfect protection circuit and strong reliability;
Seven-inch high-brightness touch color LCD, clear display under strong light, full touch screen operation, free switching between Chinese and English.
500 sets of data can be automatically saved internally.
Built-in lithium battery power supply, easy to use outdoors.
The instrument can be connected to an external printer to print measurement data, which is convenient for paperless office. (optional)
