Intelligent Mimic

One system. Eight ways to read it.

A modern industrial HMI one-line, built to be understood by engineers and procurement alike. Switch between the one-line, the physical equipment, protection, controls, communications, sensors, data and AI analytics — every layer describes the same 13.8 kV / 480 V system, and every device is linked to its compartment in the 3D switchgear.

This is a demonstration with simulated values and a brand-neutral equipment architecture. It is not a live control interface and does not represent a specific installation. In a delivered system, breaker states, measurements and events come from the protective relays, trip units, meters and sensors through the SCADA and monitoring layers described on the Automation & Controls page.
Demonstration — simulated values

Topology, breaker positions and energized paths.

Both transformers energized from the MV bus; LV Bus 1 and Bus 2 each carried by their own main. Tie open. Generator in standby.

Device panel

Select a breaker, bus, transformer or source on the one-line. Switch layers to see how the same device appears in protection, controls, communications, sensors, data and analytics.

Physical equipment ↔ digital twin ↔ data

The 3D model follows your selection: choose a device on the one-line and its compartment highlights; click a compartment and the one-line selects the device.

How it works in a real system

From device to display

Positions and trips

Breaker 52a/52b contacts and relay/trip-unit event records give position and cause. The mimic shows OPEN, CLOSED, TRIPPED, MAINTENANCE and COMMUNICATION LOST as text, symbol and color — never color alone.

Measurements

Relays, trip units and power-quality meters publish voltage, current, power, harmonics, waveform captures and sequence-of-events over IEC 61850, DNP3 or Modbus to the station gateway and historian.

Sensors

Continuous temperature sensors at stabs, joints and terminations, partial-discharge sensors on MV insulation barriers and mechanism monitors add what electrical measurements cannot see.

Analytics

Health scores, thermal anomaly detection and operating-time trends support maintenance planning. Protective functions and switching operations remain governed by approved protection, control and safety procedures.
