FAQ

1)can dc voltage arc ?

Discharge of high-capacitance test specimens must be conducted using a 100Ω/V discharge rod. During discharge, the rod cannot come into direct touch with the specimen. Instead, progressively approach the specimen until an audible hissing sound indicates the beginning of air gap ionization discharge at a certain distance. When the sound stops, the rod may be used to start the discharge, and connecting straight to the ground lead can finish the discharge.

2)is high voltage dc harmful ?

The spatial electric field distribution of high-voltage DC ions may induce variable DC potentials among humans standing in close proximity at high-voltage DC levels of 200kV and beyond, even if test workers wear insulated footwear and stay beyond the safety distance. Test personnel should avoid from shaking their hands or making touch with earthed surfaces since doing so might create a mild electric shock. This phenomena is especially visible in dry places, particularly in the winter, even though the little quantity of energy involved frequently provides negligible risk to individuals.

3)How much DC voltage is possible?

Hi, your product's voltage rating defines the highest voltage that may be achieved. Do not hesitate to ask for further specs if you require them.
