Smart Pad-Mounted Switchgear (Integrated RMU)

15 / 25 kV class · metering + automation

Entogo smart pad-mounted switchgear with integrated metering and protection

Overview

A smart pad-mounted ring main unit integrating primary load-break switchgear with secondary intelligence — instrument transformers, revenue metering, microprocessor protection, fault recording and SCADA — in one 15/25 kV class, 60 Hz unit. Designed to IEC 62271-200 and IEEE C37.74; UL/CSA certifiable.

This smart pad-mounted switchgear integrates the primary and secondary equipment of a ring main unit into one 15 / 25 kV class, 60 Hz unit built for distribution automation. Beyond the load-break switching, it carries built-in instrument transformers, revenue/energy metering, a microprocessor protection relay and high-speed transient fault recording — turning a distribution node into a monitored, remotely controllable grid-edge asset.

SCADA-ready with DNP3 and IEC 61850 communications, it supports solidly-grounded, low-resistance and resonant (arc-suppression) grounded systems for modern automated networks. Designed and built to IEC 62271-200, IEEE C37.74 and ANSI C57.12.28, with relays to IEEE C37.90 and UL / CSA certification available on request.

Key features

  • High-speed transient waveform recording for fault analysis and grid-edge monitoring.
  • SCADA / DNP3 / IEC 61850 communications for remote control and utility distribution automation.
  • Supports solidly-grounded, low-resistance or resonant (arc-suppression) grounded systems.

FAQ

Common questions

What makes this a "smart" / integrated RMU?
Beyond the primary load-break switching, it integrates the secondary equipment — instrument transformers, revenue metering, a microprocessor protection relay, high-speed fault recording and SCADA communications — so a single pad-mounted unit supports full distribution automation.
What communications protocols are supported?
The unit is SCADA-ready with DNP3 and IEC 61850 options for remote control, monitoring and integration into utility distribution-automation systems, 60 Hz.
Which standards and certifications apply?
Designed to IEC 62271-200, IEEE C37.74 and ANSI C57.12.28, with relays to IEEE C37.90. UL / CSA certification is available on request.
