Comprehensive Electrical Maintenance Solutions
Hebuma Engineering Services delivers proactive and responsive maintenance programmes designed to maximise the reliability, safety, and lifespan of your electrical infrastructure. With a team of 29 certified engineers stationed across Nigeria, we maintain critical power systems for clients in the oil and gas, manufacturing, cement, and food-processing sectors.
Our maintenance philosophy centres on preventing failures before they occur. Through a combination of scheduled inspections, advanced diagnostic techniques, and rapid-response capabilities, we help our clients avoid costly unplanned outages and keep their operations running without interruption.
Our Maintenance Services
- Preventive Maintenance Contracts — Scheduled inspections, functional testing, and servicing of switchgear, transformers, cables, and protection systems to prevent failures and extend equipment life.
- Corrective Maintenance — Rapid fault diagnosis and repair of electrical equipment failures, including root-cause analysis and implementation of permanent corrective actions.
- Predictive Maintenance — Advanced condition-monitoring techniques including infrared thermography, vibration analysis, and insulating oil analysis to detect developing faults before they cause breakdowns.
- 24/7 Emergency Breakdown Support — Round-the-clock emergency response team on standby to restore power and critical systems with minimal downtime, anywhere in Nigeria.
- Equipment Testing & Inspection — Comprehensive compliance testing and certification of electrical installations and apparatus in accordance with IEC, IEEE, and Nigerian standards.
- Transformer Oil Analysis & Servicing — Dissolved gas analysis (DGA), moisture content testing, dielectric strength testing, and on-site oil filtration and treatment to maintain transformer health.
- Circuit Breaker Maintenance — Operating mechanism servicing, contact resistance testing, timing tests, and insulation resistance measurements for HV, MV, and LV breakers.
- Battery Systems Maintenance — Impedance testing, capacity discharge testing, electrolyte analysis, and connection integrity checks for UPS and DC system batteries.
- Relay Testing & Calibration — Secondary injection testing of protection relays, settings verification, trip-circuit supervision checks, and firmware updates to ensure correct operation.
The Preventive Advantage
Reactive maintenance — waiting for equipment to fail before taking action — is the most expensive approach to asset management. Unplanned breakdowns result in production losses, safety hazards, costly emergency repairs, and accelerated deterioration of connected equipment. Studies consistently show that reactive maintenance costs three to five times more than a well-structured preventive programme.
Hebuma's preventive and predictive maintenance strategies shift the balance in your favour. By identifying and addressing wear, contamination, and early-stage faults during planned maintenance windows, we help our clients achieve higher equipment availability, lower total cost of ownership, and a safer working environment. Our detailed maintenance records and trend analysis also support informed capital expenditure planning, so you can budget for replacements and upgrades with confidence.
