Oil&Gas and Petroleum
Lightning: Oil&gas and petroleum industry characterized by traits such as flammability and explosive. So that the safety of electric and lightning protection are necessary for them . Reason :1 metal equipment and instruments including react power, frame , tank , instrument , pipeline, good conductor and cable are good conductor .2 Flammable and explosive semi-product and product placed in Production equipment on condition of high temperature and high pressure .3 Electronic equipment as DCS , UPS , PLC etc widely used in process of production, in that , integrated circuit is easily attacked by lightning. And it can’t afford the electrostatic voltage, specially for big scale modular equipment during the lightning strike . Arc fault : arc , electric spark , electricity leak,short circuit, over-voltage and accumulation static are dangerous for flammable and explosive product . Harmonic and three phase unbalance : the process of production in this industry with intensive ...
