Protection Relay Configuration

SY Power specialises in developing high-quality protection relay configurations for transmission and distribution power systems. We configure protection, control and automation functions across a range of leading relay platforms, delivering reliable solutions that meet your project requirements and industry standards. Including GE, Schneider Electric, SEL, ABB and Siemens protection relay platforms.

Native Relay Setting Files

Receive native relay setting files ready for upload directly into your protection relay. We deliver complete, professionally configured files developed using the manufacturer's software, reducing commissioning time and ensuring consistency across your protection systems. We also offer complete bench testing services for most relays.

Protection Relay Part Numbers

Selecting the correct relay hardware is critical to any project. We provide relay part number selection and verification based on your protection philosophy, communications requirements, I/O requirements and project specifications, helping ensure the right device is chosen from the outset.

Application Procedures

We develop clear application procedures that document how setting files can be uploaded to the protection relay. Along with firmware upgrades, physical relay mounting and installation guides and commissioning procedures.

Protection Setting Design Documentation

Comprehensive protection setting design documentation is produced to support every relay configuration. Documentation includes setting rationale, operating philosophy, logic philosophy and configuration records, providing complete traceability throughout the project lifecycle.

Protection Schematic Mark-Ups

We review and mark up protection schematics to support new installations, upgrades and retrofit projects. Our mark-ups clearly identify required wiring changes, protection logic updates and configuration modifications, simplifying design implementation and reducing commissioning risk.

Technical Support

Expert technical support is available throughout every stage of your project. Whether during design, commissioning, operation or troubleshooting, SY Power provides practical engineering advice to help resolve technical challenges quickly and efficiently.

Protection Relay Fault Finding

Unexpected relay behaviour can lead to unnecessary outages and extended downtime. We assist with diagnosing protection relay issues including incorrect operation, communications faults, logic errors, setting discrepancies and commissioning problems to restore reliable system performance.

Power System Fault Diagnosis

When protection systems operate unexpectedly, identifying the root cause is essential. We analyse disturbance records, event logs, oscillography and system behaviour to determine the cause of faults, investigate protection performance and recommend practical corrective actions.

Protection Logic Development

Complex protection and control schemes require reliable logic that performs under every operating condition. We develop, review and test relay logic for applications including busbar blocking, inter-tripping, breaker failure, switch-on-to-fault, automatic reclose, load shedding and custom automation functions.

IEC 61850 Configuration

SY Power provides IEC 61850 engineering services including GOOSE messaging, MMS communications, SCL file development, CID file configuration and interoperability support between protection relays, HMIs, RTUs and SCADA systems.

Bench Testing Verification

We can assist with end-to-end bench testing, scheme verification, logic validation and configuration reviews to ensure systems operate as intended under real-world conditions. Support is also available during commissioning to verify protection system performance before energisation.
