6 Frequently Asked Questions about “Circuit breaker in substation in Ethiopia”
How do distribution substations work in Ethiopia?
The distribution substations in Ethiopialower the transmission line voltages to 33 kV and 15 kV or less. The voltage is then further reduced by distribution transformers to the utilization voltages of 380 volts three-phase or 220 volts single-phase supply required by most users.
Which radial power distribution system is used in Ethiopia?
The old and simple radial power distribution system topology is used in Ethiopia domi-nantly. The primary distribution system of Jimma town takes 132 kV and steps down to 15 kV and 33 kV. There are seven outgoing feeders (two 33 kV and five 15 kV) which supplies the town and surrounding Woredas.
Why is power interruption a serious problem in Ethiopia?
Abstract. A frequent and long lasting power interruption has become a serious problem in Ethiopia. This problem has highly affected the life and economic activity of the society. The cost of power interruption to the power utility and also to the industry is very significant.
What does a distribution substation do?
Distribution substationsmonitor and adjust circuits within the system. The distribution substations in Ethiopia lower the transmission line voltages to 33 kV and 15 kV or less.
What is the average frequency of interruptions at a substation?
The average frequency of interruptions at the existing substation is1812.67 interruptions per customer per year and the average duration of interruptions is 1770.17 hours per customer per year. There is extremely high unavailability of electric power in the distribution network.
How can a power distribution substation improve reliability?
The simulation is used to evaluate the designed power distribution substation to ascertain that, it produces the desired reliability improvements. The result of the simulation shows that the designed system can advance the reliability of the overall system by improving the reliability indices values.
