JYT-A TTR tester(LCD)

  • Following IEC standard
  • Fast test speed
  • Precise test result
  • LCD screen
  • 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.

When thinking about transformer testing, TTR ranks number one in the routine maintenance testing for most engineers.  It provides a good starting point for transformer diagnostics, in that it tests that the transformer is doing what it is supposed to do.


●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!
