Vacuum Tester

In a break State ends when high voltage vacuum interrupter, with values ranging from a few microamps of leakage current, leakage current even if it is the same type of vacuum interrupter has great individual differences. In particular for vacuum Interrupters installed on the machine, because the insulation around the support there is leakage, the sum of the leakage current of the instability and unpredictability, and numerically and 10E-4Pa orders of magnitude of vacuum interrupter of the ionization current. We use two dynamic methods, excluding leakage currents to ensure whether it is mounted on the machine were to be assembled on precision of vacuum measurement of vacuum interrupter.
