Description
The PM 20 SPD test device with integrated detection of the sparkover voltage is used to test Red/Line and Yellow/Line surge arresters with integrated varistor, Zener diode or gas discharge tube. Both the sparkover performance between the connections of the arresters as well as the continuity can be tested. The results can be compared to the limit values specified in the instructions for use. In case of deviations, the arrester or protection module must be replaced.
