Current Transformer for SF6 Gas-Insulated MOF Panel
About the Product
Intended for power companies, the MOF-24 current transformer is designed to be mounted inside the SF6 gas-insulated MOF (Metering Outfit) panel of a 25.5 kV (max.) power system. With two primary coils, the current transformer offers two current ratios while maintaining the required accuracy and burden rating at each current ratio. Insulated with Araldite® epoxy resin, this indoor current transformer offers excellent electrical performance and high reliability.

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).
Suited to power transmission and distribution systems and intended to work with measuring or monitoring instruments, or with protective relays, these bushing CTs (BCTs) can also be used with GIS or in conjunction with power transformers bushings. Insulation tape or epoxy resin as insulation material.
Current Transformers / Extended Range Current Transformers (ERCTs) for Billing, 10~30kV Outdoor Type
Used for power monitoring or as part of an MOF (Metering Outfit) for a 12~36kV power system, these outdoor CTs for billing are insulated with Araldite® UV-resistant cycloaliphatic epoxy. Accuracy 0.15S~0.3; burden B-0.5. Available as Extended Range Current Transformers (ERCTs) if requested.
Cast in Araldite® UV-resistant cycloaliphatic epoxy resin, these medium-voltage potential transformers for billing are designed for long-term outdoor use in harsh conditions such as solar ultraviolet radiation, salt fog, high temperature, and high humidity. Designed to be part of a Metering Outfit (MOF).
When a power system is in operation, it is imperative that the secondary of the current transformer(s) should not have an open circuit. When an open circuit occurs, an extremely high transient voltage will be induced, which can in turn damage the current transformers and the instruments at the secondary, or even posing a threat to personal safety. This CT secondary overvoltage protector offers protection from such accidental damage caused by secondary transient voltage.
