JYT-B turn ratio tester

Visual test voltage ratio and group, Z mode test, CVT voltage ratio test and phase-shifting transformer angle test function.


● Test range is wide, the highest can reach to 5000
● Test speed is fast, finish three phase test in 10s
● Permanent time clock and date display, date storage function
● High and low voltage protection function
● Transformer short circuit, turn-to-turn circuit protection function
● Thermal printer output function, it is fast and silent
● Horizontal chassis design with convenient and practical site operation

● Totally new three-phase power supply technology to make accurate measurement in arbitrary angle and variable ratio is of phase-shifting transformer. It is your good assistant in angle measurement.

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-B 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.
