Distribution Network Automation Product Line

Distribution network automation products include sensors, switches, controllers, communication networks, and software systems that enable utilities to monitor, control, and optimize power distribution efficiently and reliably.

Core Components of Distribution Automation

1. Sensors and Measurement Devices These devices monitor voltage, current, power quality, and reactive power across the distribution network. They provide real-time data for fault detection, voltage regulation, and energy management, enabling utilities to respond quickly to network changes and maintain stability . 2. Switches and Circuit Control Devices Products such as reclosers, sectionalizers, load tap changers (LTCs), regulators, and substation capacitor banks allow automated control of power flow. They facilitate feeder switching, fault isolation, and service restoration without manual intervention . 3. Communication Networks Reliable communication is essential for system-wide automation. Solutions include mesh networks, public or private cellular networks, and intelligent connectivity platforms that link field devices to control centers. These networks support real-time monitoring, remote control, and integration with distributed energy resources (DERs), . 4. Control and Management Software Software platforms provide centralized or cloud-based monitoring, fault management, and analytics. Features include FLISR (fault location, isolation, and service restoration), Volt-VAR optimization, predictive maintenance, and outage management. Cloud solutions can report faults directly to maintenance crews, reducing response times and operational costs . 5. Consumer-Side Automation Automation at the consumer level includes smart meters, time-of-use (TOU) programming, remote service connection/disconnection, and load control. This enhances energy efficiency, demand response, and customer engagement .
