Breaker Control

A control command function is integrated in the SIPROTEC 4 7RW80 to coordinate the operation of circuit
breakers and other equipment in the power system.
Control commands can originate from four command sources:
• Local control at the device's operator panel
• Operation using DIGSI
• Remote control via network control center or substation controller (e.g. SICAM)
• Automatic functions (e.g., via binary input)
Switchgear with single and multiple busbars are supported. The number of switchgear devices to be controlled
is limited only by the number of binary inputs and outputs. Interlocking checks ensure high security against ma-
loperation and a multitude of switchgear types and operating modes are available.
