Mixed Circuit Protection (MCP) with Tata Power, India

Tata Power is the largest power generation company in India. Synaptec commissioned a Mixed Circuit Protection system on a 110 kV mixed circuit (which contains both overhead lines and underground cables) to improve post-event protection response by permitting auto-reclose on transient overhead faults, while blocking auto-reclose for faults within cable sections. This scheme demonstrates how Synaptec’s equipment can instrument up to five cable sections in series or parallel over unmatched distances from substations.
