Distribution Class Arresters

ELPRO Distribution Class Arresters are designed and tested in accordance with ANSI/IEEE C62.11 and IEC 60099-4. The standard ELPRO arrester consists of a stack of metal oxide discs housed in a sealed porcelain housing. On the end faces of each disc, a conducting surface is applied to assure proper contact and uniform current distribution.

ELPRO arresters provide exceptional dynamic and transient over voltage protection of major power system equipment. Under normal system conditions, the arrester conducts less than one milliampere. During dynamic transient over voltage the arrester conducts only the current necessary to limit the over voltage. As a result, ELPRO arresters absorb minimum energy to protect equipment insulation.

The ELPRO arrester provides both excellent protective characteristics and temporary over voltage capability. The gapless construction provides a design, which is simple and reliable while remaining economical.

ELPRO arresters are designed to meet the most demanding service conditions.
