Surge arrester Gas tube JN series operate on the gas-physical principle of the highly effective arc discharge. Electrically surge arresters Gas tube act as voltage dependent switches. As soon as the voltage applied to the Gas tube exceeds the spark-over voltage, an arc is formed in the hermetically discharge region within nanoseconds. The high surge current handling capability and the arc voltage , which is almost independent of the current, short circuit the over voltage. When the discharge has died down, the arrester extinguishes and the internal resistance immediately returns to values of several 100 M£[. The surge arrester Gas tube thus meets almost perfectly all requirements made on a protective element. It reliably limits the over voltage to permissible values, and under normal operating conditions the high insulation resistance and the low capacitance contribute to the fact that an arrester has virtually no impact on the system to be protected.
