Protecta*Lite Arrester (144 kV MCOV)


Catalog ID: 607144B7P2001

Catalog ID:  607144B7P2001
This web listing represents a sampling of typical configurations. ProtectaLite Arrester assemblies can be customized for all distribution and transmission lines.Selection of arrester MCOV size is based upon the maximum continuous voltage that is applied across the arrester in service (line-to-ground). For arresters on effectively grounded neutral systems, this is normally the maximum line-to-ground voltageExample: 84 kV on a 138 kV system. For ungrounded or impedance-grounded systems, the MCOV should be at least 90 percent of maximum phase-to-phase voltage.For more information about arrester selection, please contact your Hubbell Power Systems representative.
