Most utilities target 20–25°C temperature, 40–60% relative humidity, and consistent air circulation to protect relay panels and communication equipment. Relay room cooling and environmental optim...

High humidity can lead to micro-corrosion on PCB boards and control terminals of the protection relays. This can cause “ghost trips” or, worse, a failure to trip during a real fault.
