Critical Protection for Electrical Infrastructure
Switchgears act as the central control and safety barrier for power distribution across industrial, mining, and municipal networks. Aging insulation, oxidized contacts, or sluggish trip coils can cause destructive arc flash events or catastrophic system downtime.
Comprehensive Standards-Compliant Diagnostic Audits
Our specialist field engineers perform rigorous electrical, mechanical, and timing diagnostics on circuit breakers, busbars, and protective relays. We ensure your switchgear panels operate smoothly, trip accurately within millisecond tolerances, and satisfy international electrical safety codes.
Our Switchgear Testing & Diagnostic Solutions
From high-potential dielectric stress testing to micro-ohm contact analysis, we evaluate every electrical and mechanical component in your switchboard lineup.
Insulation Resistance (Megger) Testing
Precision Megohm measurement across busbars, circuit breakers, and insulating barriers to detect moisture contamination, dirt accumulation, and early dielectric breakdown before energization.
High-Potential (Hi-Pot) Testing
Controlled over-voltage stress testing applied for 60 seconds to prove the dielectric withstand capability of busbar insulation, phase separators, and vacuum/SF6 interrupters.
Power Factor / Tan-Delta Analysis
Advanced dissipation factor measurements that evaluate dielectric energy loss in solid and fluid insulation, pinpointing microscopic internal degradation and aging.
Contact (Ductor) Resistance Testing
Micro-ohm resistance testing across closed breaker contacts and bus connections to locate surface oxidation, contact pitting, or loose bolting that causes dangerous hot spots.
Continuity & Protective Earthing Audits
Verifies the low-resistance integrity of earth bar connections, panel earthing bonds, and control wiring circuits to guarantee safe ground-fault current paths.
Mechanical Interlock Verification
Rigorous physical checks of mechanical and electrical safety interlocks to confirm proper switching sequences, preventing accidental racking or switching under load.
Breaker Timing & Trip/Close Coil Diagnostics
High-precision timing analysis measuring opening, closing, and total arc clearing speeds down to milliseconds, combined with trip and close coil current profiling to eliminate sluggish mechanism operation.
