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
