Jh2702 Transformer Single/Three Phase Manufacturing Portable Turns Ratio Meter TTR Tester

Product Description

Product Interview:
For the power system, transformers are the core equipment in the system, so the long-term and reliable operation of transformers will be related to the stability and reliability of the entire system. Before the newly installed transformer is put into operation and in accordance with the preventive testing regulations of State Grid, it is required to conduct regular turns ratio or voltage ratio tests on the operating transformer. The traditional variable ratio bridge operation is cumbersome, the reading is not intuitive, and necessary conversions need to be made. The test result is only the value of one phase change ratio. This transformer ratio tester overcomes the shortcomings of traditional ratio bridge testing. The screen adopts a large high-resolution LCD display screen, which is convenient for on-site use. It has a Chinese menu prompt function, easy and intuitive operation, and can complete three-phase ratio testing in one go. The testing speed is fast and the accuracy is high.
Performance Characteristics:1. The three-phase CNC sine inverter power supply output has soft start and soft stop functions, so the testing speed is fast and the accuracy is high.
2. Three phase transformer, single-phase transformer, PT, CT, Z-type transformer ratio, group, polarity testing function.
3. CT ratio polarity testing function.
4. It has angle difference testing function during single-phase testing.
5. The tap changer can be tested up to 99 gears.
6. Wide testing range, up to 10000.
7. High and low voltage reverse connection reminder.
8. Output short circuit reminder.
9. Non power-off clock and date display; The data storage method is local storage, with 100 test data pieces. The stored data can be transferred to a computer (PC);
10.Thermal printer printing function.
11. Small size, light weight, convenient for carrying and use.
