Abstract: The components in the overhead electrical network are continuously exposed to the physical environment of varying weather conditions. If the weather around an electrical network is regular and consistent over a specific period, then the weather can be modelled as usual or single weather (SW). However, in practice, the overhead electrical network is always subjected to varying weather conditions, such as typical weather and adverse weather. Then, the weather is modelled as two weather (TW) models. Adverse weather (AW) can cause significant physical damage to the components, resulting in higher average failure rates and longer durations for power restoration. Without considering weather conditions, the reliability assessment of the overhead electric power distribution system can be overly optimistic, influencing planning and design decisions. The investigation of system reliability under two weather conditions provides insight into the effect of percentage failures that occur in severe weather conditions on the average interruption duration per customer per year and the amount of energy not supplied per customer per year. This paper evaluates the reliability of a radial distribution system (RDS) under single weather conditions and two weather scenarios. Further, the effect of the fault passage indicator placement on RDS under SW and TW is also evaluated. A fault passage indicator (FPI) is a device that indicates and communicates the fault’s location to the operator, thereby reducing fault identification time and improving system reliability by reducing outage duration.
