Definition

Reclosing used to quickly

restore power and limit outages

for transient(self-clearing) faults

Sectionalising

used toisolate sections of the network

for permanentfaults

Up to 70% of faults

are transient

The downstream device changes protection

group in anticipation of the change in the

direction of the power flow, goes to SingleShot (no auto-reclose) mode and trips.

The tie device also changes protection group

depending on which side the power was lost (source or

load), goes to Single Shot (no auto-reclose) mode and

closes upon receiving a close request.

Picks up, executes trip/reclose sequence & goes

to lockout. It will then send a trip request to its

downstream device using Modbus P2P
