Four disciplines, one specialist team.
From relay logic and protection philosophy to power system studies, control and automation systems, and reliability-centred maintenance — supporting projects from design through commissioning and into operation.
Design, coordinate, and modernize protection
Relay and control engineering built around your network's real configuration and operating requirements.
- Relay logic design
- Relay setting calculations & coordination
- Protection philosophy development
- ATS design (relay-internal, PLC, or hardwired / IEC 61850)
- Protection system upgrades
Analyze, verify, and protect the network
Rigorous studies that validate design decisions and keep people and equipment safe under fault conditions.
- Load flow analysis
- Short circuit analysis
- Arc flash studies
- Motor starting & stability analysis
- Earthing system design
Maintain what matters, when it matters
Risk-based maintenance strategy that aligns effort with how your equipment actually fails, rather than with the calendar.
- RCM strategy development
- Criticality & FMECA analysis
- Maintenance program optimization
- System-wide reliability strategy
Automation written by power engineers
PLC and SCADA work for switchboards and substations, engineered by people who also calculate the fault levels and set the relays.
- ATS & Main-Tie-Main control schemes
- Substation SCADA & ECMS
- Power management & fast load shedding
- Legacy PLC migration & retrofit
