Operations & Maintenance (O&M) Services

Proactive Power Asset Care & Lifespan Optimization

Unplanned power outages and electrical asset failures can lead to massive operational losses in critical industrial facilities. ISTS provides tailored Operations & Maintenance (O&M) solutions for Low Voltage (LV) and Medium Voltage (MV) power systems, safeguarding infrastructure health and operational continuity.

Combining routine physical servicing with advanced predictive diagnostics (such as thermal imaging and online partial discharge monitoring), our competent technicians and engineers identify potential failure modes long before they result in costly downtime or safety hazards.

Core Capabilities

Scheduled Preventive Maintenance (PM)

Comprehensive cleaning, busbar torque checking, contact servicing, and insulation resistance measurement for switchboards and transformers.

Infrared Thermography & Diagnostics

Non-intrusive thermal imaging of energized electrical connections and switchgear to identify localized overheating and loose connections early.

24/7 Emergency Breakdown Support

Rapid-response field teams equipped for fast fault diagnosis, breaker swapping, emergency cable jointing, and system restoration.

Partial Discharge (PD) & Asset Health Monitoring

Periodic and continuous condition monitoring to track insulation degradation in high-voltage cables and MV switchgear panels.

Reliable Asset Care Aligned with Statutory Standards

ISTS structures O&M service level agreements (SLAs) around your plant’s operational schedule—minimizing planned shutdown durations while satisfying statutory requirements mandated by Suruhanjaya Tenaga (ST).

Every maintenance routine includes detailed inspection reports, updated baseline trending data, and recommended corrective action plans to help facility managers prioritize capital expenditure and optimize asset lifecycle costs.

Technical FAQs

Medium Voltage (MV) switchgear and transformers typically require comprehensive shutdown maintenance every 12 to 24 months, while non-intrusive thermal scanning and visual inspections should be performed semi-annually or quarterly.

Our breakdown support includes on-call competent engineers, mobile diagnostic test sets, emergency cable repair kits, and rapid deployment to isolate electrical faults and restore plant power safely.

Yes, we offer customized SLAs featuring 24/7 dedicated response times, zero-downtime thermal monitoring, and synchronized maintenance schedules designed specifically for Tier III/IV data center uptime standards.
