Answer Posted / Taruna Saxena
In parallel operation, both NGRs (Northern Grid Relays) do not close simultaneously as they are designed to protect separate power systems. If both systems experience a fault and both NGRs close at the same time, it would result in an over-relaying situation, which can cause instability or even system collapse.
