Smart Utility Meters (Electric, Gas, Water)

Valve Control (for Gas and Water Meters)
Motors actuate shut‑off valves remotely for safety, non‑payment, or maintenance. Gearboxes provide torque multiplication for secure, reliable valve operation.

Switching Mechanisms (Electric Meters)
Actuate internal relays or switches to connect or disconnect load remotely. Enables remote service activation and deactivation with precision control.

Tamper Detection
Motors can periodically move sensors or mechanical components to test for tampering. Supports advanced anti‑tamper and diagnostic functionality.

Meter Calibration and Adjustment
Gearmotor systems fine‑tune meter settings mechanically, enabling automatic calibration without manual intervention.

Electrical Protection Systems

Reset Mechanisms
Automatically reset relays or breakers after a trip, improving uptime and reducing manual intervention.

Tripping and Isolation Functions
Actuate trip mechanisms in response to overloads or faults — such as in motor‑driven latching relays.

Control Actuators for Switchgear
Compact motors control breakers, isolators, and disconnects in low‑ and medium‑voltage systems.

Time‑Delay Mechanisms
Gearboxes are used to implement mechanical delay functions for relay operations and sequencing.

    Control Systems (Smart Grids, Substations, Industrial Panels)

    Motorised Potentiometers or Setpoint Adjustments
    Used in analog and hybrid control systems to adjust thresholds or calibration settings automatically.

    Positioning of Sensors or Antennas
    Motors move small sensor arms or antennas for optimal signal alignment or measurement accuracy.

    Mechanical Feedback Systems
    Provide positional feedback in closed‑loop systems, including tap changers and adjustable controllers.
