LWB 6410 fully automatic transformer ratio group tester Features: 1. Fully automatic transformer ratio measurement function, which can automatically complete the measurement of three-phase transformer ratio, winding wiring method, and group label without setting any parameters, making it easy to operate with just one press. 2. It can automatically measure, continuously measure three-phase, measure single-phase transformer voltage ratio, and calculate transformation ratio error. 3. Transformers that can measure various connection groups such as Y/y, Y/d, D/y, D/d, ZN/y, ZN/d, etc. 4. It can measure the wiring mode and group label of high and low voltage side windings, especially suitable for measuring unknown groups of transformers. 5. Complete protection functions, with quantitative output overload protection and overvoltage protection. 6. When the excitation current is high, the output voltage can be automatically reduced to adapt to transformers with low rated voltage and high excitation current. 7. Automatically track and measure the tap position of the on load switch, without the need for repeated input of parameters. 8. Small size, light weight, accurate measurement, and fast speed. 9. It can store or print all measurement results. This instrument is equipped with a built-in power on memory and a micro printer, which can store measurement data for a long time and can be viewed and printed at any time. 10. Equipped with RS-232 interface, it can communicate with computers and enhance data statistics and management functions. 11. Calendar without power outage, clock function.
