Description

Selection of Electrical Equipment's for Hazardous AreaYou will gain the following from this Course:A good understanding of terminology used in Hazardous areaUnderstanding hazards of using electrical equipments in the presence of flammable gases, vapors & dust.A basic knowledge of explosion protection.Hazardous Area classifications.Selection of electrical apparatus that can be used in a given Hazardous Area.An understanding of Hazards & Control measures.Course Overview:Hazardous areas exist in every power plant. Following proper design rules and anticipating how the plant will be operated can avoid creating mixtures of gases that could explode or catch fire.Hazardous area classification is a rigorous method of determining where an explosive environment may be present. The codes and standards used in this process provide guidance for selecting, building, and installing electrical equipment in that area. In general, hazardous areas (HAs) are defined by:The type of hazard or hazardous material.The likelihood of its presence in flammable concentration.The auto-ignition temperature of the hazardous material.Correct selection of electrical equipment for hazardous areas requires the many information's such as:Classification of the hazardous area ;Temperature class or ignition temperature of the gas or vaporWhy is it necessary to identify electrical hazardous area in process plant ?Hazardous areas are classified solely for the purpose of ensuring the safe and proper specification and installation of electrical/ electronic equipment located within them.What you will Learn:Hazard, Hazardous Area and Control measuresUnderstanding Fire TriangleCriteria for Classifications of Hazardous areasClassifications of Hazardous areas with ExampleTypical Hazardous areasTemperature ClassesBasic concepts of Explosion protection in Hazardous AreaCriteria for Selection of Electrical apparatus for Hazardous AreaSelection of Electrical apparatus According To ZonesSelection of Electrical apparatus According To The Ignition Temperature Of Gas Or VapourSelection of Electrical apparatus According To Apparatus GroupingSafe Areas for Electrical installationINGRESS PROTECTION (IP)
