Switchgear Maintenance

Switchgear maintenance is how we protect the central distribution assets of your facility. When primary switchgear assemblies are neglected, accumulated particulate, loose hardware, and dielectric breakdown can escalate into arc-flash hazards, bus damage, and catastrophic facility outages. Our focus is to keep switchgear clean, properly torqued, and functionally verified so it responds correctly under high-stress fault conditions.

We begin with formal switchgear inspection, examining metal-clad and metal-enclosed sections, main bus bars, incoming and outgoing terminations, overcurrent protective devices, secondary control wiring, and mechanical interlocks. Our technicians screen for discoloration, oxidation, insulation deformation, and contamination that indicate thermal stress or developing electrical faults.

Next, we execute switchgear cleaning, de-energizing and removing dust, particulate, and conductive contaminants that cause insulation tracking or flashover. This preventative measure eliminates common failure modes, particularly in unconditioned electrical rooms or industrial processing environments.

Once switchgear sections are clean, we proceed with switchgear testing. We utilize electrical diagnostics and operational functional checks to verify the response of draw-out breakers, disconnect switches, auxiliary control circuits, and protective relays. This confirms that all switching equipment will isolate, open, and clear faults under actual load conditions.

When defects are detected, we execute switchgear repairs—correcting mechanical binding in racking mechanisms, torque-verifying or replacing compromised terminations, and resolving control wiring faults that hinder normal switching or automatic transfer functions. For obsolete, burned, or non-serviceable equipment, we manage component replacement, installing compatible, code-compliant parts to maintain switchgear integrity.

This maintenance protocol mitigates unscheduled downtime, satisfies NFPA 70E and OSHA safety requirements, and verifies to facility engineers and inspectors that the primary electrical distribution infrastructure operates dependably.
