Voltage Ratings of Surge Arresters - Powell Ind

other surges. It is important that surge arresters of the correct voltage rating be used. The proper voltage rating depends on the system line-to-line voltage, the method of system grounding, and the type of surge arrester used. Older designs of surge arresters generally consist of silicon carbide resistor blocks in series with air gaps.
