High voltage cable failure
High voltage cable may cause breakage, short circuit and high voltage breakdown. High voltage cable fault is the most common breakdown of main insulation layer. Once this fault occurs, it causes little X-ray, and more is no X-ray. After the failure, due to the increase of the earth current, the mA meter is punching top, the transformer has a large overload sound, fuse fuse, power supply overlap, the breakdown part can see discharge spark, and can smell the smell of ozone or rubber burning.
Once the breakdown of high voltage cable breaks down, it is necessary to stop and repair and not be tested too much, so as to avoid further expansion of the fault.
