Testing the zero value of the current

A value of zero current may lead to disruption of power supply in automatic high-voltage contact switches. Today it may seem incredible that the high-voltage circuit can be interrupted other than arc discharge.

Operation of all automatic pin switches based on the impact of receding from each other contacts, while between them there is arc discharge. The effect of zero current is an indicator for pressure, temperature, density, ionization, plasma flow, etc.

Measurement of the zero current values are used to understand the effect of the arc and to determine the main parameters necessary for the successful interruption of the current
