Well-coordinated protection is the difference between a contained fault and a plant-wide outage. We engineer numerical relay schemes — overcurrent, distance, differential, busbar and breaker failure — with carefully graded settings and verified trip logic so faults are cleared fast and selectively.
Layered on top of protection, our automation logic handles auto-changeover, load shedding, interlocking and sequence control, turning a passive switchyard into an intelligent, self-aware network that operators can trust.
View protection servicesOur substation automation systems are built on a clean station, bay and process-bus architecture and engineered to IEC 61850 for true multi-vendor interoperability. GOOSE messaging replaces hard-wired trip and interlock signals, cutting copper, reducing failure points and speeding up commissioning.
Integrated SCADA brings every breaker, feeder, transformer and relay into one real-time picture. Operators monitor, alarm and control from a single HMI, while historians and reports give engineers the data they need to plan maintenance and prove compliance.

From PLC and RTU configuration to HMI development, we program control systems that are safe, repeatable and easy to maintain. Every sequence, interlock and alarm is structured for clarity so your team can operate and extend the system with confidence.
Before anything is energised, we test it. Secondary injection relay testing, electrical testing of cables, transformers and switchgear, and structured commissioning ensure every scheme performs exactly as designed — backed by detailed, audit-ready reports.
See PLC & testing servicesWe pair specialist power-system knowledge with a delivery process built around reliability, documentation and on-time commissioning.
A team focused exclusively on protection, automation and digital substations — not generalists.
IEC 61850, IEC 60870 and IEC 60255 engineering done right, with interoperability proven in testing.
Every project ships with settings, SCL files, test reports and as-built records for audits and future work.
Pre-tested logic and FAT-proven schemes keep site time short and energisation on schedule.
Our work is judged on one thing: how reliably your power system performs. Here is the value our protection, automation and testing services deliver to your operation.

Answers to common questions about our engineering services.
A protection and automation system is the combination of numerical relays, intelligent electronic devices (IEDs), control logic and communication networks that detect electrical faults, isolate them selectively and automate the operation of a substation or plant. It protects equipment and personnel while enabling remote monitoring and control through SCADA.
Yes. We design and deliver complete substation automation systems covering station-level HMI and gateways, bay-level controllers and protection IEDs, and process-bus interfaces. Every SAS is engineered to IEC 61850 for interoperability and built around your single-line diagram, protection philosophy and SCADA requirements.
All our digital substation work is engineered to IEC 61850. We handle SCL configuration (SSD, SCD, CID), GOOSE messaging, MMS reporting and time synchronisation, and we validate interoperability between multi-vendor IEDs during factory and site acceptance tests.
We integrate SCADA with both new and legacy assets. Our engineers map your existing relays, RTUs and PLCs, configure the right protocols (IEC 61850, IEC 60870-5-101/104, Modbus, DNP3) and build a unified, real-time SCADA front end without disrupting running operations.
Relay testing verifies that every protection element operates correctly. We perform secondary injection testing of pickup, timing, directional and differential elements, check trip and interlock logic, and document the results in a structured commissioning report that becomes part of your asset records.
We serve power generation, transmission and distribution utilities, industrial and process plants, renewable and solar installations, water utilities, metro and railway systems, oil and gas, and manufacturing OEMs — anywhere reliable protection, automation and electrical testing is required.
After an initial consultation and review of your single-line diagram and scope, we typically mobilise engineering within days. WhatsApp us or request a quote and our team will respond promptly with a tailored proposal and timeline.
Yes. We offer annual maintenance contracts (AMC) that include periodic relay testing, SCADA and PLC health checks, firmware management and priority on-site support to keep your protection and automation systems dependable year-round.
