Corinex has launched its Grid Intelligence Node (GIN), a monitoring device designed to give utilities near-real-time visibility into conditions across low-voltage feeders.
The system can help distribution system operators identify available grid capacity for new electrical loads, including electric vehicle (EV) charging infrastructure. It can also detect emerging constraints and verify the impact of grid upgrades or other interventions.
GIN combines broadband powerline communications with integrated voltage, current and power-quality monitoring. It is designed for installation in secondary substations, street cabinets and lateral branches.
The device measures three-phase voltage and current with an RMS error of 0.5% or less. It also monitors power, power factor, frequency and energy consumption.
Power-quality monitoring includes harmonics through the 51st harmonic, total harmonic distortion, voltage sags and swells, overloads and phase imbalance. GIN provides one-minute operational snapshots and 15-minute energy aggregates, with optional one-second reporting.
The system connects directly to 230/400-V networks and supports split-core current transformers or Rogowski coil sensors. Data can be transmitted using MQTT, Ethernet, Modbus RTU or Modbus TCP.
Measurements from GIN can also feed into Corinex Plexigrid Intelligence, which combines field data with grid modelling and optimization. The platform can use this information to improve low-voltage state estimation and determine how much additional capacity is available for loads such as EV chargers.
This can help utilities determine whether charging demand can be accommodated by the existing network or whether additional grid reinforcement or load-management measures are required.
GIN uses existing low-voltage power lines to carry communications and measurement data through Corinex broadband powerline technology. This allows utilities to add feeder-level monitoring without installing a separate communications network.
The Grid Intelligence Node is available for utility evaluations, pilot projects and commercial deployments.
