Reliability & Engineering Risk Analysis

Failure Mode & Root Cause

Overheating of components

Cause: Inadequate ventilation, dust accumulation blocking airflow, or excessive ambient temperature causing thermal stress on electrical components like PLCs, drives, and contactors.

Corrosion and electrical short circuits

Cause: Moisture ingress due to poor sealing, condensation from temperature fluctuations, or exposure to corrosive atmospheres leading to oxidation of terminals, PCB tracks, and relay contacts.

Maintenance Indicators

Audible buzzing, arcing, or unusual humming from relays, contactors, or transformers indicating loose connections or failing components.
Visible signs like discoloration, melting, or smoke from wiring insulation, burnt smell, or LED indicators on devices showing fault codes (e.g., overload, ground fault).

Engineering Tips

Implement regular thermographic inspections using infrared cameras to detect hot spots early, and ensure cabinet cooling systems (fans, filters, air conditioners) are clean and functional to maintain optimal operating temperatures.
Maintain proper sealing integrity with gaskets and cable glands, use desiccant breathers to control humidity, and apply anti-corrosion coatings on internal metal surfaces in harsh environments.
