As part of a modernization program for 400 kV substations, Efacec deployed Moxa's PT-7728 IEC 61850-3 Ethernet switches in the transmission substation automation system. These switches connect with protection relays and other intelligent electronic devices (IED), and form a ring topology that is highly self-healing in the event of a network failure…
The utility company sought to create a resilient grid that could sustain a blackout at one substation without impacting other substations by deploying Moxa's PT-7728 to each substation in a star topology…
CPC deployed Moxa's PowerTrans series Ethernet switches to connect with protection relays for collecting data. In the event of an emergency, the PowerTrans switches will send out a warning relay for an immediate shutdown…
In order to improve the reliability of the system, the operator sought to modernize the entire automation network, including a substation automation network that was originally installed in 2000…
One of the largest steel factories in China needed proper communication control units for data processing and protocol conversion with the devices at remote field sites. These computers would replace the IPCs and can easily create a distributed system at the front-end site with a centralized management platform at the back-end control center...
