JYT Portable Transformer turns ratio tester (TTR)
JYT portable transformer turns ratio tester (TTR tester) is a new generation of ratio tester based on modern industrial design concept, JYT is total 1.6kgs only so it’s very suitable for spot and long time testing work, with powerful built-in lithium battery which can support more than 800 testing times with one charge. JYT TTR tester is easy carrying, efficient, accurate and fast test speed(1.2s). It is an ideal tester for variable turn ratio testing in power generation, transmission, substation, industrial and transformer manufactures.
1. JYT With powerful built-in lithium battery which is suitable for field testing work, can perform more than 800 times testing on a single charge.
2. It with 8 connection poles meets the requirements of transformer turn ratio testing from distribution transformer to power transformer, current transformer (CT), voltage transformer (PT) and Z-type connection transformer.
3. has 5.6 inch color high brightness touch screen, so the tester can be used both indoor and outdoor.
4. With mechanical key for "run/stop".
5. JYT equipped with the function of monitoring and protecting the Battery.
6. With "flash disk" interface for exporting data and blue tooth communication function.
7. It has the functions of high and low voltage reverse connection protection, short circuit protection of transformer and inter-turn short circuit protection.
JYT select series NEC Microprocessor to make sure high testing accuracy.
