MiCOMho Agile P443, P445, P446
Distance Protection Systems
The MiCOMho Agile P443, P445 and P446 relays operate with advanced load blinding and disturbance detection techniques, such as power swing blocking, to ensure stability when no tripping is required. Whether protection is required for lines, cables or hybrids of grounded transmission and distribution circuits, the MiCOMho Agile P443, P445 and P446 relay characteristics allow for versatile deployment.
Enhanced Ethernet board module with switchable Ethernet redundancy delivered in a single model.
The new board module is supported on P443, P445 and P446 SW 76, 79, 86 and 87.
It supports PRP, HSR and RSTP in one model, allowing a single P40 model to be used in any application requiring redundant Ethernet communications. The new module is designed to handle high density traffic in the IEC 61850-8-1 network, with time latency halved. Larger architecture digital substations can also be supported, with up to 50 nodes now possible in HSR rings.
Key Features & Benefits:
Transmission and distribution systems are essential for the safe, sure routing of power from generation sources to consumers. However, exposed overhead lines transporting power are by nature sometimes vulnerable and prone to fault. In the case of a faulty circuit, the Agile range provides speedy protection to trip and isolate it, thereby preventing further damage.
Each relay model contains multiple main protection elements: distance, delta directional comparison protection and directional earth/ground fault unit protection (DEF). This permits simplified application and spares holdings, because the relay can be adopted as the standard protection platform.
The MiCOMho Agile P443 and P445 are suitable for feeders controlled by a single circuit breaker. The MiCOMho Agile P446 is suitable for complex installations where feeders are controlled by two circuit breakers such as ring bus/mesh corner formations and the breaker-and-a-half configurations.
