Manual WIP1Woodward2. GeneralThe WIP1 is a self-powered time overcurrent relay with multi-characteristics and including earth fault protection. Definite time and inverse time tripping characteristics can be selected.Due to its wide setting ranges, the tripping characteristic can be selected to protect a wide variety of differentequipment.The WIP1 does not require any aux. voltage supply, consequently it can also be used for switchboards without auxiliary power supply. It takes its power supply energy from the C.T. circuits and provides the trippingpulse energy to the circuit breaker.The WIP1 is a robust protective device that is designed for a long-time operation with minimum maintenanceefforts even under extreme climate conditions. Our experience with WI Line self-powered protective relaysshows that the MTBF („Mean Time Between Failures“) is approx. 200 years (calculated based on data up toyear 2012), and there are WIP1 relays being in service at our customers’ sites for more than 22 years evenunder harsh climate conditions.DOK-TD-WIP1E Rev.

Directional Relay Coordination Coordination of directional overcurrent relays involves setting of relays one by one so that at each stage the relay coordinates with its primary relay. In a loop, the last relay to be set is the very first, in which initial setting were assumed. Relay coordination activity in a mesh system is iterative.

By placing the connector screw in the desired tap, the relay will just close its contacts at the tap value current.
Three-phase Directional Overcurrent (67) Each one of the three-phase overcurrent stages of the P127 can be independently configured as directional protection with specific relay characteristic angle (RCA) settings and boundaries. Each directional stage has instantaneous (start) forward/reverse outputs available. Directional Overcurrent Tripping .
