SAS Powertech, a leading electrical engineering solutions provider, offers comprehensive relay coordination studies alongside top-tier electrical safety audit services in India, helping industries achieve optimal protection and regulatory compliance.
What Is a Relay Coordination Study?
A Relay Coordination Study is a critical engineering analysis designed to ensure all protection devices—like relays, circuit breakers, and fuses—operate in a coordinated manner during electrical faults. The goal is to isolate only the faulty section of the electrical system, thereby minimizing disruption to the rest of the network.
Key Objectives of a Relay Coordination Study Include:
- Ensuring proper grading of time-current characteristics
- Preventing nuisance tripping
- Improving system reliability
- Protecting critical equipment and personnel
- Optimizing the performance of protection relays and breakers
This study is essential for industries like power generation, oil and gas, manufacturing, commercial complexes, data centers, and any facility with complex electrical networks.
Why Are Relay Coordination Study Services Important?
Without proper coordination, an electrical fault in one area can result in complete plant shutdowns, equipment damage, or even fire hazards. These failures not only cause operational losses but also pose serious safety risks.
Benefits of conducting Relay Coordination Study Services in India include:
- ✅ Improved Protection System Efficiency
Avoid unnecessary outages by ensuring that only the affected section trips during a fault. - ✅ Enhanced Personnel Safety
Reduce arc flash risks and ensure faster isolation of electrical faults. - ✅ Reduced Equipment Damage
Quick fault clearance protects expensive machinery and extends asset life. - ✅ Regulatory Compliance
Helps industries meet safety and energy audit norms mandated by electrical inspectorates. - ✅ Cost Optimization
Prevents financial losses due to downtime, maintenance, and insurance claims.

Process of a Relay Coordination Study
Here’s how a typical study is executed by SAS Powertech:
- Data Collection
Collection of single-line diagrams (SLDs), equipment specs, relay types, and load details. - System Modeling
The electrical system is modeled using specialized simulation tools. - Fault Analysis
Calculations of possible fault currents at various nodes and scenarios. - Relay Settings Review
Study of existing relay settings and logic. - Coordination Plotting
Time-current characteristics (TCC) curves are plotted to evaluate coordination between devices. - Optimization and Recommendations
Relay settings are fine-tuned, and a final report is delivered with graphs, logic diagrams, and compliance notes.
This structured approach ensures zero ambiguity and maximum clarity for plant engineers and safety officers.
