Quantification and Analysis of Human Errors Across the Life Cycle of Electrical Installations

The modern power system has different installations and as they are manmade, their consistency and security are dependent on human intervention. This research study has been carried out to analyse different types of faults in Electrical Installations according to life cycle and human related intervention in the various stages of the life cycle of an electrical installation. Secondary data has been collected to derive the results regarding the electrical faults in Electrical Installations according to life cycle and human intervention in the various stages of the life cycle of an electrical installation. It is found that electrical failures majorly occur in transformers, switchgear and rotating machines. By categorizing electrical faults into its life cycle, the different human errors were realised. The stages of machine life cycle found are design, assembly, inspection, operating and maintenance. By constructing a network and combining it with the life cycle of the installation, different human involvements have been recognized that leads to faults and accidents.
