TEBB-600A ratio tester overcome the traditional shortcomings of the ratio bridge test,easy to operate and intuitively. It can complete a three-phase ratio or turn ratio test once, take less time with high accuracy.

Features:

(1) Adopt precision three-phase inverter measurement power supply to measure the voltage, which eliminate the harmonic effect of the main voltage , more accuracy.

(2) Adopt 3 phase output voltage,3 phase input voltage and 3 phase measuring at the same time, can automatic identification of transformer connection group 0 -11 very easily.

(3) Suitable for various transformers, with the function of testing the Z type transformer.

(4) Using precision three-phase inverter power supply, has the high and low voltage reverse connect protection and transformer inter-turns short circuit protection, tap-changer protection and output short circuit protection functions, increase the stability of instrument.

(5) After inputting the rated parameters, can automatic measure transformer turns ratio, error and tap-changer points, especially for asymmetric tap-changer points, also can accurately test the position of the transformer tap-changer, can measure up to 99 points of tap-changer

(6) With Micro-printer, USB and RS232 interface.
