Relay innovation enhances solar PV inverter performance

Solar PV inverters typically have a lifespan of five to ten years, and in some cases up to 15 years.

Adaptive Distance Relaying for Distribution Lines Connecting Inverter

Distribution lines are generally protected by overcurrent relays. With the integration of an inverter-interfaced solar photovoltaic (PV) plant having a current-limiting feature, the fault current seen by the relay on the PV side of that feeder becomes comparable to the load current. The conventional overcurrent relaying principle is not suitable for distribution line
