The T-203 automatic transformer turns ratio tester(TTR tester) can measure the high/medium voltage (if any), high/low voltage ratio, and phase of various high-voltage transformers; Can adapt to the needs of various large, medium, and small transformer ratio tests (including zigzag transformers, rectifier transformers, electric furnace transformers, phase-shifting transformers, balance transformers, Scott and inverse Scott transformers).
The T-203 automatic transformer turns ratio tester(TTR tester) is equipped with a large capacity lithium-ion rechargeable battery and a highly stable three-phase variable ratio power supply. Color LCD display, graphical user interface, vector diagram display and wiring judgment. Store test data, with printer, PC data management software. Automatic load current protection to prevent damage to the instrument caused by excessive load or short circuit in the test circuit.
