has a small capacity, it is easy to burn out when discharging large capactive
samples.
● The suspending conductor in the test area and a certain range of surrounding areas
should be grounded during the test to prevent the high voltage electric field against
producing high voltage to its inductive charging, endangering the safety of people and
equipment.
● when the test voltage is higher, although the test persons wear insulating shoes and are
in the area beyond the safe distance, due to the influence of high-voltage dc electric field
spatial distribution, it will make several adjacent standing human bodies with different DC
electric potential. Do not shake hands with each other or touch the ground with your hands,
otherwise there will be a slight electric shock phenomenon, this phenomenon is more
obvious in dry areas and winter, but generally will not harm people because of the low
energy.
●
When carrying out tests with possible discharge shock (such as breakdown test
and discharge test), please avoid using computer online operation control, because
discharge shock may damage the upper computer.
