Cable Fault Detection using Multi-Zone Protection
In hybrid circuits containing both overhead lines and underground cable sections, it is advantageous to determine in which section an electrical fault has occurred. This enables an operator to auto-reclose (AR) in the event of a transient OHL fault, or to block auto-reclose in the event of a permanent cable fault. This is not typically possible if simple distance protection schemes are deployed, which will typically result in some ambiguity in identification of the faulted section, rendering auto-reclose prohibitively risky.

The importance of monitoring power quality across all turbines
Wind farm power quality (PQ) is monitored to confirm that the output is within the permitted range stipulated by grid compliance regulations. Operations and maintenance (O&M) services also require PQ measurements to monitor flicker, voltage drop, oscillations, and harmonic resonance. Follow the link to read more.
