Discharge testing machine

With regards to partial discharge test
AC partial discharge test equipment ACPD-05X

By microwave patch antenna system
Not affected by the test circuit realizing
a highly sensitive partial discharge test! !

As the use of inverter coil will increase in the future, such as house hold appliances, automotive coil, industrial commodity, the examination of such coils will spread and must be done.

Easy to understand screendisplay

The graph of applied voltage (AC) and electric discharge signal is displayed on the screen in real time. The condition of electric discharge generating is observable during an examination. Moreover, the memory of the graph under examination is also memorized into the main part after display and judgment are possible.

Variegated graph-analysis function

Applied voltage PD characteristic graph

Transition of the voltage value during AUTO examination and electric discharge level display.The electric discharge exceeding a threshold value level is displayed in red.

Applied voltage Qmax characteristic graph

The electric discharge level in the applied voltage during AUTO test is displayed.It is graph-ization about partial discharge inception voltage (CSV) and partial discharge extinction voltage (CEV).

Electric discharge generating accumulation frequency characteristic graph

The electric discharge generating accumulation frequency characteristic in the electric discharge level generated
during AUTO test is displayed.

Features

The electromagnetic waves generated from partial discharge with a microwave patch antenna system are detected directly.
Installing an antenna near the test coil, high sensitivity partial discharge test can be performed
Since handling is easy ,the introduction to production line can be facilitated .
The automation of the partial discharge test becomes possible.
Working efficiency improves by the convenient function required for evaluation of a partial discharge test. Break down voltage (CSV), electric discharge extinction voltage (CEV), electric discharge level (PDpeak), electric discharge occurrence probability confirmation k (PDpuls), etc .
Since the electric discharge signal is indicated by a waveform, it is possible to use it visually ,clearly and easily.
