Integrated Primary-Secondary Ring Main Unit

12 kV RMU

The integrated primary-secondary ring main unit answers the State Grid standard for integrated distribution equipment, combining electromagnetic voltage and current transformers, an energy-metering module and high-speed transient fault recording in one 12 kV intelligent unit. It supports low-resistance or arc-suppression-coil grounded systems for modern, automated ring-main networks.

Key features

  • Integrated primary and secondary equipment in one intelligent unit.
  • Built-in electromagnetic voltage and current transformers.
  • Energy metering and high-speed transient fault recording.
  • Developed to the State Grid integrated-equipment technical standard.
