Describe the important features of the power distributions system. Outline the advantages of high voltage distribution system (HVDS).
The power distribution system is an essential part of the electricity grid that ensures the delivery of electricity from substations to end consumers, such as homes, industries, and businesses. It plays a crucial role in the final stage of the electrical grid, converting electrical energy from high-voltage transmission lines into usable lower-voltage electricity. The key features of a power distribution system include:
-
Substations: These are intermediate facilities that step down the voltage from high transmission levels to lower levels suitable for distribution. Substations include transformers, switchgear, and circuit breakers for controlling the flow of electricity and ensuring safety.
-
Distribution Lines: The distribution lines carry the electricity from substations to consumers. These can be either overhead lines or underground cables, and they operate at lower voltages compared to transmission lines. These lines are typically categorized as primary and secondary lines. Primary lines carry electricity at medium voltage, while secondary lines provide low voltage electricity to end-users.
-
Transformers: Distribution transformers are used to reduce the voltage to a _________ __________ __________ ___ _______ _______ _________ ______.
