1. Product Introduction Switchgear is one of the most important electrical equipment in power plants and converting stations, who moving and fixed contacts and busbar joints are always under high voltage stress. Because of oxidation, corrosion, loosening and ageing, the surface resistance act contact points and joints increases, the temperature rises and leads to overheating, thus affects the insultation and shorten the equipment operation life time. The HQ-12 type fiber optic temperature monitoring systems from Herch Opto offers real time & condition based temperature monitoring of switchgear hot spot, which gives situational awareness of switchgear health and keep equipment from catastrophe failure and ensure a continuous supply of power. 2.
