Product Application
JZZV1-10 combined transformer is a new type of high-voltage electric energy metering device. It is composed of two fully insulated voltage transformers with the same voltage ratio to form a three-phase "V-V" connection; A and C phases are respectively connected in series with current transformers with the same current ratio. It is cast in one piece with special low-temperature epoxy resin and uses seamless silicone rubber as external insulation. This product is suitable for electric energy metering or relay protection in power lines of 10kV and below, and for assessment of power grid line losses.
Technical Parameters
