Potential Transformer for SF6 Gas-Insulated MOF Panel
EPF-20SH
Intended for power companies, this indoor single-phase epoxy-cast potential transformer is designed to be mounted inside the SF6 gas-insulated MOF (Metering Outfit) panel of a 25.5 kV (max.) power system. With an added tap in the secondary winding, this PT can offer two voltage ratios (120/60:1).
About the Product
Intended for power companies, the EPF-20SH single-phase potential transformer is designed to be mounted inside the SF6 gas-insulated MOF (Metering Outfit) panel of a 25.5kV (max.) power system. With an added tap in the secondary winding, this PT can offer two voltage ratios (120/60:1) and allows easy switching between the two, while maintaining the accuracy and burden rating of 0.3Y at each voltage ratio. Insulated with Araldite® epoxy resin, this indoor potential transformer offers excellent electrical performance and high reliability.
