Draft Standard for Transient Overvoltage Protection of DC Electrification Systems by Application of DC Surge Arresters

P1627/D5-2018 发布历史

The standard covers application of dc surge arresters for transient overvoltage protection of dc transit electrification systems. These dc transit electrification systems include light rail@ heavy rail@ street car@ and trolley bus systems. This standard covers selection and application of MOV gapless surge arresters to divert surge energy away from the transit system components. It does not cover low-voltage surge protection devices (SPD) that are required within dc traction power system equipment such as rectifier units@ vehicle propulsion system or other sensitive components of the dc transit system. Purpose It is the purpose of this standard to provide uniform practices for lightning and switching transient overvoltage protection of dc transit electrification by proper selection of dc surge arresters based upon the surge environment and site conditions of the transit system. Such a standard will allow the use of surge protective devices to dc transit systems to avoid insulation failure due to transient overvoltage. Transientovervoltage protection is just as important as short circuit protection. This standard will minimize equipment damage caused by transient over voltages@ increase system reliability that will result in reduced maintenance.
