Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Contact arcing and erosion
Cause: Inadequate contact pressure, contamination from dust or moisture, or mechanical wear leading to poor electrical contact and localized overheating during operation.
Insulation degradation and tracking
Cause: Environmental factors such as humidity, dust accumulation, or chemical exposure, combined with electrical stress, causing breakdown of insulating materials and potential flashover.
Maintenance Indicators
  • Audible buzzing, crackling, or popping sounds from the switchgear enclosure during operation
  • Visible signs of overheating such as discoloration, blistering, or charring on insulation, busbars, or contact surfaces
Engineering Tips
  • Implement regular infrared thermography surveys to detect abnormal heating patterns in contacts, connections, and insulation before failure occurs
  • Maintain strict environmental control with proper sealing, desiccant breathers, and regular cleaning to prevent contamination and moisture ingress that accelerates insulation breakdown
