High Voltage Direct Current (HVDC) converter stations are the substations where direct current (DC) electricity at transmission voltages is converted (inverted) to lower-voltage alternating current (AC). Use of DC for bulk transmission has advantages over AC transmission that can include:
A fire at one of these substations can put operating personnel at risk plus interrupt power supply to thousands of homes and businesses. Protecting these stations from fire present challenges ordinary fire and smoke detection systems cannot meet. Traditional fire safety systems suitable for commercial settings are too slow for adequate protection of these critical infrastructure installations. Also, they are reactive devices, reducing the ability of staff to manage the threat before the discharge of suppression systems.
As is occurring in other high-hazard, critical process operations, Authorities Having Jurisdiction (AHJ) are increasingly insisting on the use of tested, listed or certified systems for HVDC operations. The reason is simple; the AHJs know that systems that meet or exceed codes and standards are the best way to maximize protection. Applicable codes, standards and best practices include:
A complete system from Det-Tronics is an ideal solution for these demanding applications. Backed by more than 45 years of solving the most challenging high-hazard fire and gas safety solutions, you can rely on Det-Tronics certified and listed solutions to protect against fire hazards that pose severe threats to personnel, facilities and operational continuity.
