Blueprint for Safety, Efficiency, and Compliance

The relay coordination study gives a clear picture of how protective devices are working in coordination. We help address the critical pain points in your facility's power system.

What We Deliver

Safety of Personnel

Our relay coordination study ensures that fault is isolated at the right location, thereby enhancing safety by mitigating arc flashes.

PROACTIVE SUPPORT

Proactive Support for Protection Coordination Study

A Relay Coordination Study in Canada entails holistic support from the team. To avoid cascading faults, we practice zero tolerance for errors.

Technical support in relay setting optimization and TCC curve analysis.
Functional Support in system modeling and coordination adjustments.
Strategic support in relay testing, troubleshooting, training, and knowledge transfer.
Compliance standards implementation support.
Software support using advanced tools like ETAP for proper relay coordination.

Our Relay Coordination Process

Protective Device Inventory

We catalog all protective devices including circuit breakers, fuses, relays, and trip units with their current settings.

Short Circuit Study Integration

We use fault current data from the short circuit study as the basis for coordination curve development.

TCC Development

Our engineers develop time-current coordination curves using ETAP for all protective devices in the system.

Coordination Analysis

We identify coordination gaps, miscoordination, and opportunities to reduce arc flash incident energy.

Settings Optimization

We recommend optimal relay and trip unit settings balancing protection, selectivity, and arc flash reduction.

Report Delivery

We provide a complete report with TCC curves, recommended settings, and implementation guidance.

Frequently Asked Questions

A relay coordination study in Canada is an engineering study that evaluates electrical system behaviour against CSA Z462, IEEE 1584, and the Canadian Electrical Code. Carelabs engineers analyse your facility, produce labelled single-line diagrams, and deliver a compliance report used to specify PPE, clearances, and protective device settings for safe operation.

Carelabs relay coordination study reports comply with CSA Z462 (workplace electrical safety), IEEE 1584-2018 (arc flash calculation), the Canadian Electrical Code (CEC), and IEC 60909 where applicable. Every deliverable cites the clauses used so your safety officer can audit the methodology.

CSA Z462 requires a relay coordination study to be reviewed every 5 years, or sooner if the electrical system has been modified — for example, after a transformer replacement, utility upgrade, breaker change-out, or significant load addition. Carelabs offers annual walkthrough reviews for clients with evolving facilities.

Carelabs delivers relay coordination study in Canada using CSA Z462, IEEE 1584, and Canadian Electrical Code methodologies. Our P.Eng team produces labelled drawings, incident-energy calculations, and documented compliance reports — contact us for scope specific to your facility.

Relay Coordination Study is important in Canada because energised electrical work is the leading cause of industrial burn injuries, and CSA Z462 makes documented analysis mandatory before workers approach live equipment. A proper relay coordination study identifies hazards, specifies PPE, and proves due diligence to provincial OHS inspectors.

Relay Coordination Study cost in Canada varies with facility size, number of buses, voltage levels, and data completeness. Typical projects range from a few thousand dollars for small sites to tens of thousands for multi-substation plants. Carelabs scopes every project from equipment count and drawing quality — contact us for a fixed quote.

A typical relay coordination study for a Canadian mid-size facility takes 3 to 6 weeks from kickoff to final report. Timeline depends on data-gathering completeness, number of buses modelled, field verification scope, and report revisions. Carelabs delivers a locked schedule with milestones at kickoff.
