Combination transformer

Outdoor combination transformer is an outdoor high-voltage energy metering device, suitable for energy metering or relay protection in 10kV power lines, assessment of power grid line losses, and segmented assessment of substations. Three phase "V/V" connection composed of two fully insulated voltage transformers with the same transformation ratio; A. C phase is connected in series with current transformers of the same current ratio. The JLSZW-10W series three-phase three element combination transformer is a new generation product improved on the basis of the three-phase two element "V/V" wiring.
