Description
This type of voltage and current combined transformer (also known as electric energy metering box) is used for active and reactive energy measurement in AC 50H, rated 35kv three-phase power lines. It is suitable for outdoor substations in rural areas, and can also be used in small substations and distribution stations of industrial enterprises. This product can replace the JLS-35 oil-immersed electric energy metering box.
