TEBB-600A Three-phase Transformer Turn Ratio tester
1. Product discription
TEBB-600A model Turnratio tester overcomes the shortcomings of traditional bridge method. The monitor adopts big screen with lattice liquid crystal, which has the function of indicating by menu, operating easily and directly. It can finishtest of three-phase voltage ratio or turns ratio once, fast testing withhigh precision
2.Product features
(1) Instrument internal adopt precision three-phase inverter measurement power supply instead of the single-phase mains supply as measuring 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 65K True Color Module LCD display, each operation step with English prompt, and the operation can be completed just by prompt and no need of manual work.
(7) With Micro-printer, USB and RS232 interface.
(8) With sealed water-proof and shock-proof sturdy hand-case, be suitable for field testing.
