Corrosion monitoring for power distribution cabinets

Corrosion monitoring for power distribution cabinets is a critical method for preventing equipment failures caused by oxidation, moisture, or harmful gases; it achieves this by tracking the internal environment, metal structures, and the condition of electrical connections in real time.
Key Monitoring Parameters and Indicators
•    Ambient temperature, humidity, and condensation: High humidity and temperature fluctuations can easily lead to condensation inside the cabinet, resulting in degraded insulation and short circuits.
•    Corrosive gases: Substances such as hydrogen sulfide, sulfur dioxide, or high concentrations of salt spray accelerate the chemical corrosion of copper busbars, silver plating, and terminal blocks.
•    Connection oxidation and temperature rise: Poor contact or minor corrosion increases electrical resistance, leading to abnormally high temperatures.

Integrated Monitoring Method Using Three Sensing Technologies

•    •  Temperature, humidity, and condensation sensors: Collect real-time data on the cabinet's internal micro-environment and trigger dehumidifiers or heaters when thresholds are exceeded.
•    •  Corrosion rate monitoring: Periodically analyze the extent of corrosion caused by gaseous pollutants in the equipment room or around the cabinet by using copper and silver test coupons, in accordance with relevant standards (such as ANSI/ISA-71.04).
