1. Self powered: Powered by lithium batteries, it is very convenient for on-site testing without the need for additional power supply.
2. Powerful: It can measure the transformation ratio polarity of PT and the transformation ratio group of transformer. It can measure the polarity/group of single-phase and three-phase, and complete the measurement of AB, BC, CA three-phase transformation ratio, group, error, tapping position, tapping value and other parameters in one go. It can automatically identify the group number.
3. Tapping test: It can quickly measure the transformation ratio and transformation ratio error at each tapping switch position. The rated transformation ratio only needs to be input once, and the transformation ratio error at each tapping position can be calculated without repeated input.
4. At the same time, it has two functions: turn ratio measurement and operating voltage ratio measurement. The operating ratio can more accurately reflect the actual value of the voltage ratio of the transformer and PT in actual operation.
5. Good vibration resistance: The use of military connectors enhances vibration resistance.
6. Adopting a 3.5-inch high-definition true color LCD screen, the display data effect and vector image effect are intuitive and delicate.
7. The test source used in this instrument is a standard sine digital source that is digitally synthesized, with a distortion of less than 0.1% and is not affected by mains power.
8. Internally equipped with high capacity lithium-ion rechargeable batteries, on-site testing can be completed without any power supply. One full charge can perform more than 800 consecutive measurements.
9. Small size, light weight, and easy to carry.
10. The instrument has three versions of software: Chinese, English, and Chinese English.
