Manufacturer: Rockwill
Rockwill’s Distribution Automation Switchgear is an intelligent medium-voltage switching solution designed for modern distribution networks. It integrates vacuum circuit breakers or load break switches, current/voltage transformers, digital protection relays, motorized operating mechanisms, fault indicators, and remote terminal units (RTU/FTU/DTU) in one coordinated assembly.
It enables remote monitoring, control, fault detection, isolation, and service restoration, helping utilities and industrial users build a reliable, self-healing, and efficient smart grid.

It is Rockwill’s intelligent medium-voltage switchgear that combines switching, protection, metering, and communication functions. It allows utilities to monitor and control distribution equipment remotely and automate fault handling.
It detects faults, isolates the faulted section, and restores power to healthy sections automatically or through SCADA-assisted operations, reducing outage duration and scope.
Common options include IEC 61850, DNP3.0, Modbus RTU/TCP, and IEC 60870-5-101/104, with fiber, Ethernet, 4G, or 5G communication depending on project requirements.
Yes. It can coordinate with distributed generators, energy storage, and microgrid controllers to support bi-directional power flow, islanding, and safe grid interconnection.
