Relay Platforms
Five divisions, one specialist team.
Four engineering disciplines and a training division — from relay logic and protection philosophy to power system studies, control systems and reliability-centred maintenance, and on to building the same capability inside your own team.
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
Build the capability inside your own team
Corporate training in protection, IEC 61850, testing and commissioning — taught by the engineers doing the project work, not by full-time lecturers.
- Protection fundamentals and setting calculation
- IEC 61850 and substation automation
- Relay testing, commissioning and event analysis
- Programs written against your own scope of work
Have a protection or power system challenge?
Work directly with the engineers doing the analysis — clear scoping from the first conversation.
