Fire Detection for Transformer Stations

Fire detection solutions for Transformer Stations, such as Flame detection and suppression systems, must detect flames rapidly to prevent a widespread fire within the sub stations and transformer stations. This is crucial, as fires in sub- or transformer stations have a severe impact on power supply to customers and affects the utility company’s assets and revenue. The fires are also hazardous to personnel and the general public.

Sub- and transformer stations use a variety of equipment and systems, each of which present their own set of fire risks. Fires may involve DC valves, outdoor or indoor oil-insulated equipment, oil-insulated cables, hydrogen- cooled synchronous condensers or PCB insulation. The oil used in oil-insulated equipment may ignite due to electrical malfunction. Internal arcing may occur within the oil due to infiltration of water, failure of core insulation, exterior fault currents or tap-changer failures.
