JYT-A Transformer TTR tester

  • Product description: JYT-A TTR 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.

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.

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