This series of three-phase integrated current transformers is suitable for installation on three-phase bushings of ring main units and pole-mounted switches. It is applied for measurement and relay protection of three-phase current and zero-sequence current, as well as zero-sequence current detection and protection of multi-cable circuits.
The iron cores and secondary windings of the current transformers are vacuum-cast with high-quality epoxy resin inside flame-retardant plastic housings, featuring excellent moisture resistance, stable performance and maintenance-free operation.
The rated current ratio and rated burden of the measuring windings and composite windings for this series can be customized and manufactured according to customer requirements.
