Transformer Turns Ratio Meter
Introduction
YT-A transformer turns ration meter is suitable for the turns ratio measurement of power transformers upto 1000kV, current transformers, voltage transformers and Z type transformers. It has L-N voltage measurement, great convenience for wiring connection, fast test speed and high accuracy.
Features
- Touch panel, easy for operation;
- Current measurement function, much more sensitive to detect the short circuit in the turns;
- Fast test speed, one time wiring can fulfill 3 phase turns ratio measurement within 10 s;
- 50 test data storage;
- LCD, thermal printer, RS485 communication port and USB port;
- With transformer short circuit protection, turns short circuit protection, wrong connection of HV and LV terminals protection;
