Protection and Selectivity Review
We review the protection system so a fault is safely contained and only the affected section is disconnected.
WHAT PROBLEM DOES IT SOLVE?
The problem this service resolves
Uncoordinated protective devices can shut down the whole facility on a minor fault, or fail to protect equipment fast enough.
SERVICE SCOPE
What the review covers
Protection relay functions
Time-current coordination
Earth fault protection
Tripping times
Cable and equipment withstand
Operational continuity for critical loads
OUR WORKING METHOD
How we work
Documents and data are collected, the technical review is carried out, findings are classified by severity, and solution options with their decision conditions are presented to the employer.

CLIENT BENEFIT
Why it pays off
The Protection and Selectivity Review service reduces technical uncertainty, ensures decisions are recorded and justified, and surfaces costly problems early — before they appear during construction or operation.
FROM THE FIELD
A minor fault no longer shuts the whole plant
The protection settings were not coordinated: any fault tripped the main breaker. We corrected the time-current grading so only the affected feeder drops — production stays up.
