XHBB128B Series transformer transformation ratio meter
Description
The XHBB128B Series transformation ratio meter series can provide two power supply ways: external AC220V and internal battery, which facilitate the user to carry out testing. 
Performance and characteristics
1.The interface applies the intelligent type touch way, operation is simple and convenient. The circuit applies the new generation of the complete digital scheme, which can ensure stability of the instrument for long term.
2.Testing speed is quick, transformation ratio testing of three phases can be completed only through one wiring, taking only 10 seconds.
3.Carry out testing of CT, PT, CVT and Z shape connected transformer.
Applicable to transformation ratio measurement of the power distribution transformer to the 1000KV transformer, the current transformer (CT), the voltage transformer (PT) and the Z shape connected transformer.
4.Several short circuit measurement ways are set up in internal area, which facilitate fault judgment.
Non-power off clock and date display, the instrument can save 50 groups of data, data during powering-off will not be lost.
5.Large screen colorful liquid crystal display, data are clear and readable, print by the thermal printer. 6. 6.RS485 communication interface and U disk memory interface.
7. high voltage and low voltage reverse connection protection function, which has short circuit, turn to turn short circuit protection functions of the transformer and mis-connected 380V protection function of the power supply.
8.Optional external AC220V and internal battery AC / DC power supply, it is not necessary to connect the external AC power supply and carry out testing
