System for acquiring corrosion state of electrical contact surface of high-voltage switchgear cabinet, has sensor to determine corrosion sate of electrical contact surface, based on electrical resistance change of specific material
System for acquiring corrosion state of electrical contact surface of high-voltage switchgear cabinet, has sensor to determine corrosion sate of electrical contact surface, based on electrical resistance change of specific material
The system (1000) has a sensor (300) that is provided to monitor electrical contact surface (200) of specific material made of tin, silver and copper. The corrosion sate of electrical contact surface is determined based on electrical resistance change of specific material. The electrical contact surface and sensor are arranged in a switchgear cabinet (100).
