Protective Device Coordination

Protective Device Coordination

Relay Coordination is the selection and/or setting of Relay in order to isolate only the portion of the system where the abnormality occurs. The
majority of Relay coordination is used in an electrical power system where the system voltage is more than 11 kV.

Relay Coordination Is the Selection And/or Setting of a Relay in Order to Isolate Only The Portion Of The System Where The Abnormality Occurs.

The Majority of Relay Coordination Is Used in An Electrical Power System Where the System Voltage Is More Than 11 KV. With the help of relay coordination, facilities can ensure the minimum loss conditions.

In protective device coordination, these devices must be coordinated to ensure that the device nearest the fault point will operate first. To meet this requirement, protective devices must be rated or set to operate on minimum overcurrent, in minimum time, and still be selective with other devices on the system to achieve effective protective device coordination.

Protective Device Coordination

Why Elegrow

As engineering consultants, we have carried out many industrial safety audits and root cause analyses across industries and have observed that the major reason for nuisance tripping is the improper setting of the protective devices in the system. Hence we understand the importance of effective protective device coordination at the ground level
