Electrical equipment doesn't stay as good as the day it was installed — it degrades slowly, steadily, and silently. Contacts wear, insulation dries out, connections loosen, and contaminants accumulate. Without a structured maintenance program, this degradation goes undetected until it causes a failure — and electrical failures are rarely clean or predictable. Our routine maintenance services identify problems before they escalate, plan interventions during scheduled outages, and keep your electrical infrastructure performing at peak efficiency for decades.

01What Equipment Do We Maintain?

Our maintenance services cover all major electrical equipment:

▸Switchgear & Circuit Breakers — Mechanical operation testing, contact wear measurement, insulation resistance testing, breaker timing, and mechanism lubrication for MV and HV switchgear.
▸Protection Relays — Periodic relay calibration and functional testing to ensure trip settings haven't drifted and the relay firmware is current.
▸Cables & Terminations — Insulation resistance trending, sheath testing, thermographic scanning of cable trays and termination points under load.
▸Motors & Drives — Bearing vibration analysis, winding insulation testing, alignment checks, and drive parameter optimization for MV and LV motors.
▸UPS & Batteries — Battery discharge testing, impedance measurements, UPS functional testing, and charger verification for standby power systems.

02Why Routine Maintenance Matters

Planned maintenance is vastly more cost-effective than reactive repair:

▸Cost Savings — A $50 contact replacement during planned maintenance is orders of magnitude cheaper than replacing a transformer destroyed by a phase-to-ground fault caused by deteriorated insulation.
▸Extended Life — Proper maintenance extends equipment life by 20–50%, deferring capital replacement expenditure.
▸Predictable Outages — Scheduled maintenance allows planned outages coordinated with production, avoiding emergency shutdowns that cost far more than the maintenance itself.
▸Regulatory Compliance — Many jurisdictions require periodic testing of electrical safety equipment, earthing systems, and fire protection systems.

03Our Approach

We combine preventive and predictive maintenance for maximum effectiveness:

1. Preventive Maintenance

Scheduled inspections, cleaning, lubrication, bolt tightening, and functional testing based on manufacturer recommendations and industry best practices.

2. Predictive Maintenance

Condition monitoring techniques — thermography, vibration analysis, DGA, partial discharge, and insulation trending — to detect problems before they cause failure.

3. Corrective Maintenance

Targeted repairs identified through monitoring — contact replacement, insulation repair, bearing replacement, and corrective upgrades to address design weaknesses.

4. Reporting & Tracking

Detailed maintenance reports with photographic evidence, test results, trending data, and recommendations for planned outages or capital improvements.

04Scope of Maintenance

Our maintenance programs include:

▸Annual Maintenance Agreements — Comprehensive annual contracts covering scheduled maintenance visits, emergency response, and spare parts management.
▸Thermographic Surveys — Quarterly or bi-annual infrared scanning of switchgear, cable trays, busbars, and connections under load using calibrated thermal cameras.
▸Relay Testing Program — Scheduled relay calibration and functional testing on a rotating schedule to ensure all protection relays are tested within 3–5 year cycles.
▸Earthing System Testing — Periodic verification of earthing resistance, grid integrity, and step/touch voltage measurements for safety compliance.

05Standards & Compliance

✓IEEE C57.12.00 — Maintenance Guidelines

✓IEC 60078 — Circuit Breaker Maintenance

✓NFPA 70B — Electrical Equipment Maintenance

✓ISO 13371 — Condition Monitoring

06Why H-Infinity

We maintain electrical systems for over 50 sites across the GCC, including refineries, petrochemical plants, power generation facilities, and commercial developments. Our maintenance approach is data-driven — we don't just follow calendar-based schedules but use condition monitoring data to optimize maintenance intervals. Our annual maintenance agreements offer fixed pricing, guaranteed response times, and comprehensive reporting that makes electrical maintenance a predictable operating cost rather than a surprise expense.
