RE: Moisture in Switchgear
Causes for moisture if it is a air conditioned room:
1. Air leaks from control cables entry- Arrest with foam seals
2. Negative pressure in the room - Adjust air return dampers.
Silica gel is not a solution for high moisture codensation. Instead space heaters are more preferrable. But I haven't seen any space heater in cable compartments of MV/HV switchgear.
