MiCOMho Alstom P443, P445 and P446: High Performance Distance Protection
The MiCOM Alstom provides fast, highly selective protection for overhead lines, and the capacity to trip and isolate any faulty circuit.

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 MiCOM Alstom range provides speedy protection to trip and isolate it, thereby preventing further damage.

Multiple main protection elements and simplified application
The MiCOMho Alstom 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 Alstom P443, P445 and P446 relay characteristics allow for versatile deployment.
