What Is Switchgear?
Switchgear is a vital component in any power system, designed to isolate and protect specific circuits without disrupting the entire electrical network.
Common in Bay Area substations and industrial environments, switchgear helps prevent serious hazards by containing fault currents and short circuits.
At SES, we specialize in switchgear maintenance and repairs, including medium voltage switch components. Common issues such as defective space heaters can allow moisture to build up, leading to dangerous phase-to-phase or phase-to-ground faults.
Routine inspections and planned maintenance outages—typically every 1 to 3 years—are key to preventing unexpected failures
Switchgear vs. Circuit Breakers
While often confused, switchgear and circuit breakers are not the same. A switchgear assembly may include:
-
Switches
-
Current and potential transformers
-
Meters
-
Copper or aluminum bus components
Both switchgear and circuit breakers must be tested and maintained to ensure they can safely carry and interrupt electrical current as designed.
Switchgear Testing FAQ
Q: How often should switchgear be tested?
A: We recommend testing every 1–3 years, depending on the environment and system criticality. Harsh or outdoor conditions may require more frequent maintenance.
Q: What can happen if switchgear isn’t maintained?
A: Poor maintenance can lead to system failures, arc faults, or even electrical fires—putting both personnel and equipment at risk.
Q: Do you provide service outside of San Jose?
A: Yes! SES serves the entire Bay Area, including Santa Clara, Fremont, Oakland, Palo Alto, and more.
Q: Can testing be done during business hours?
A: Yes, but we also offer after-hours or scheduled outage support to minimize disruptions to your operations.
