What is right of way maintenance?
Right of way maintenance is the clearing out of the way of the transmission lines by doing removal of trees or trimming of trees to prevent short circuits and an outage (Beaty, 1998). 2. What voltage(s) is used directly by customers? Utilization voltages such as 480 V and 120/240 V are used directly by the consumers (Beaty, 1998). 3. What voltage(s) are used to transmit electricity long distances, why? Extra high voltages (EHV) such as 345, 500 and 765 kV are used to transmit electricity at long distances because it is economically feasible and at lower voltages (Beaty, 1998).
4. How is voltage changed during the transmission process? Voltage is changed during the transmission process by the substations. Substations lower down the voltage which will be distributed to the consumers (Beaty, 1998). 5. During maintenance on transmission lines workers often directly contact the lines. How is this possible without being electrocuted? Workers are energized at the same level as the conductor by the use of a conducting device so that no current flowing in his body would kill him. Jut like birds landing on wires and not get electrocuted (Beaty, 1998). 6.
What are the four main categories of design taken into account during the transmission system design? Categories like electrical design, mechanical design, structural design, and miscellaneous features of transmission line design should be taken into account during transmission system design (Beaty, 1998). 7. What are the four basic arrangements for sub-transmission circuits? Which two provide the best continuity of service? The four basic arrangements for sub-transmission circuits are radial, loop, grid, or tapped tie. The best continuity in service can be provided by a loop or a grid system (Beaty, 1998).
8. Provide an in-depth description of the purpose for substations and what benefits they provide? Substations are very important in a transmission system. First, substations have all the important equipments and devices needed for the transmission. Theses equipments range from equipments that transform voltage level up to the equipments that monitor and protect the whole transmission system (Beaty, 1998). The main work of a substation is to lower down voltage levels to a certain amount so that it can be transmitted to the ultimate consumers.
Also substations are made to provide transmissions in emergency situations like the mobile substations. These substations are highly movable and can be moved quickly in to a place where transmission is altered. These substations can give transmissions whenever an emergency happens like outage due to flood so that the substation that it replaces can be repaired or reconstructed (Beaty, 1998).
