Centralized 87L
Enables true 87L line differential protection with centralized handling of up to six terminals and flexible interface combinations.
Why SIPROTEC Process bus?
Traditional substations rely on extensive copper wiring and analog connections, leading to high installation costs, limited flexibility, and increased risk of errors. As grid demands grow and digitalization accelerates, utilities face challenges in adapting legacy systems to modern requirements. Without a digital process bus, substations struggle with scalability, maintenance, and integration of advanced protection schemes. SIPROTEC 5 process bus addresses these needs by digitizing all analog and digital values close to the process, enabling flexible, scalable, and future-proof substation automation. This solution reduces wiring, enhances reliability, and supports seamless integration of new technologies, ensuring efficient and secure grid operation.
Key benefits
Cost savings
Less copper cabling, faster installation, and commissioning
Optimized design
Smaller CT design due to the shorter distances and thus smaller burdens, less CT cores are required
Simplified Engineering
Typical-based engineering with reusable SV, GOOSE, MMS configurations
FEATURED CAPABILITIES
Features & functions
all
Multi-terminal 87L
The restriction to two line-terminals has been lifted and therefore allows the use of constellations with process bus up to 6 line-terminals.
