Main features for TTR Meter
1. Using a three-phase precision inverter power supply as the measurement voltage, which eliminates the harmonic influence of the mains voltage during measurement and makes the measurement more accurate. no influence when working power source is generator.
2. The three-phase output voltage is adopted to improve the test speed. The angle between phases can be measured, and the wiring group 0-11 can be automatically identified.
3. It is suitable for a wide variety of transformers, especially suitable for the measurement of Z-type transformers, rectifier transformers, grounding transformers, electric furnace transformers, phase-shifting transformers, balance transformers, etc.
4. With high and low voltage reverse connection protection, transformer turn-to-turn short-circuit protection, tap switch failure protection, output full short-circuit protection, and increase the stability of the instrument.
5. After inputting the rated parameters, it can automatically measure the transformer ratio, error value and tap position of the tap changer. Especially for tap changers with asymmetric tapping, the accurate position of the tap changer of the transformer can also be accurately measured. A tap switches capable of measuring 99 tap positions.
6. Adopt 7-inch high-definition color touch screen LCD, modular display, good visibility even under strong light.
7. Can be connected to an external printer to print measurement data, environment friendly.
8. High quality multifunctional engineering plastic box is cold-resistance, high temperature resistance, water proof, shake proof, which is suitable for field test.
