Protection Coordination Studies
Ensuring selective fault isolation to minimize system disruption and maintain reliable power system operation
What are Protection Coordination Studies?
Protection coordination ensures that protective devices isolate only the affected portion of a power system during faults, such as short circuits or overloading, to prevent unnecessary outages or equipment damage. The primary goal is to minimize system disruption while maintaining reliable operation by setting protective devices to respond promptly and selectively to faults.
Why Protection Coordination Studies Matter
Essential for maintaining system reliability and equipment protection
Device Optimization
Optimizing settings for protective devices to ensure reliable and selective operation
Service Continuity
Minimizing scope and duration of service interruptions from equipment failures
Equipment Protection
Preventing equipment damage and associated costs during system faults
Fault Clearing
Optimizing fault clearing times and developing time-current coordination curves
Our Protection Coordination Process
Comprehensive methodology for reliable protection system design
Data Collection
Gather comprehensive data including single-line diagram (SLD), protective device specifications, trip settings, short circuit currents, transformer/line ratings, CT/PT details, and system parameters.
System Modeling
Build a detailed and accurate model using industry-standard software such as ETAP, PSS®E, or PSCAD/EMTDC to represent the complete protection system.
Study Preparation
Develop comprehensive simulation scenarios aligned with client requirements and industry standards to evaluate protection coordination under various operating conditions.
Reporting
Compile and deliver a comprehensive technical report with detailed findings, recommendations, and time-current coordination curves to ensure optimal protection system performance.
