Data Center Electrical Maintenance Services

We deliver specialized electrical maintenance services for mission-critical data center infrastructure, ensuring high availability, power redundancy, and compliance with international standards. Our maintenance programs are aligned with Uptime Institute guidelines, OEM recommendations, and applicable IS/IEC standards.

Our scope covers preventive, predictive, and corrective maintenance of complete power systems, including HT & LT switchgear, transformers, ring main units (RMUs), UPS systems, battery banks, static transfer switches (STS), power distribution units (PDUs), bus ducts, DG sets, synchronization panels, and automatic transfer schemes (ATS).

Maintenance activities include insulation resistance testing, contact resistance measurement, thermographic scanning, relay testing, battery impedance testing, harmonic analysis, load profiling, earth resistance measurement, and power quality assessment. We perform detailed health checks of protection systems, interlocks, redundancy paths (N+1 / 2N), and failover sequences to ensure seamless power transfer during abnormal conditions.
