JYT-A Transformer turns ratio tester

  • Product description: JYT-A turns ratio tester has fast testing speed, all three-phase test finished in 10 seconds, Z shape joint transformer testing, CVT transformation ratio measurement, wtih 160V,10V output voltage.

●Can visual measure value of turn ratio and joint groups.
●Fast test speed, complete all three-phase testing in 10 seconds.
●Can test transformer in Z shape joint.
●CVT transformation ratio testing.
●Permanent clock& date display function, data storage function, high and low voltage transformer protection function, protection function from transformer short  circuit and interturn short circuit
●The function of current display can judge the short circuit among circle

●With 160V/10V output voltage switch, two output voltage can test transformer with low rated voltage and large no-load current.

JYT-A Power transformer turn ratio tester (turn ratio meter)is a professional testing equipment which is suitable for transformer service industry, substation maintenance, power transformer /distribution transformer maintenance company, 3 phase transformer testing, and other transformer testing field, Kingrun series TTR tester such as JYT-A and JYT-F tester has reliable capability and accurate testing result selected by SIEMENS and ABB transformer manufacture and transformer service companies.

High performance of MPU (microprocessor) can provide high precise data and fast calculation:

LCD screen provide clear display for all tested value.

Thermosensitive printer provide fast and clear tested value printing.

JYT-A supply RS485 and USB interface for data transmission.

Testing clips are made from pure copper with punch forming , the surface is nickel plating, the handle is insulating, the testing clip is safe, easy handling and well connection (13Meters).

We supply a infrared temperature measuring gun with tester for free!
