About Us
PowerSphere Engineering Limited is a specialist electrical engineering company focused on Protection Engineering, Commissioning and Testing of mission-critical power systems across offshore, industrial and utility environments.
We support clients operating high-risk and high-value electrical infrastructure by delivering technically sound, compliant and defensible commissioning outcomes. Our work spans LV, MV and HV systems up to 132kV, supported by deep expertise in protection design, testing and power system analysis.
Project Planning & Engineering Assurance
Scope definition, drawing and protection philosophy reviews, fault level calculations, grading studies and verification against applicable standards.
Commissioning & Protection Testing
Factory and site pre-commissioning support, primary and secondary injection testing, CT/VT testing and full functional verification of protection schemes.
Energisation, Handover & Lifecycle Support
Controlled energisation, load trials, regulator-ready documentation, handover and ongoing maintenance strategies including upgrades and fault investigations.
Protection Testing & Functional Verification
Primary and secondary injection testing, CT/VT verification, relay logic validation and switchgear functional testing to confirm correct operation under fault conditions.
Energisation & Load Trials
Controlled energisation, system monitoring and load trials to verify stability, interfaces and performance before full operational release.
Documentation, Handover & Compliance
Preparation of commissioning dossiers, as-built documentation and regulator-ready records to ensure full compliance and auditability.
Lifecycle Support & Maintenance Strategy
Periodic testing, brownfield upgrades, fault investigations and life extension strategies to maintain long-term system reliability.

OUR VALUES
OUR EDGE
We combine deep engineering expertise with global reach to deliver reliable, high-risk power system assurance.
Our Philosophy
Our philosophy defines how we approach every engagement, ensuring safety, precision and reliability at every stage of delivery.
Planning → Design Review → Factory Acceptance Support → Pre-Commissioning → Protection Testing → Energisation → Load Trials → Handover → Maintenance Strategy
OUR TECHNICAL COMPETENCE
Our technical competence reflects the depth and breadth of our protection, commissioning and testing expertise across complex power systems.
PowerSphere Engineering Limited exists to remove uncertainty from complex power systems. We work at the point where protection, commissioning and operational risk intersect, ensuring critical electrical infrastructure performs safely and predictably from first energisation through its operating life.
Our engineers operate across offshore, industrial and utility networks, applying rigorous engineering judgement, detailed testing and robust documentation to LV, MV and HV systems up to 132kV. Every engagement is driven by precision, compliance and long-term reliability—because in critical power environments, assurance matters as much as performance.
