Discuss the design, construction and installation of both solid and oil-filled high voltage cablee, and describe the techniques which may be used to minimise sheath losses in such cables. Indicate the limitations of conventional cables for bulk power transmission.

Expert Solution

The solid filled high voltage cables do not have good impregnation. However, in case of oil-filled cables impregnation is even possible before or after sheathing. Solid cables do have formation of voids, while this is not in case of oil-filled cables. Moreover, oil filled cables are a good indicator in case there is any defect in the cable, as the leaking oil gives us the indication about the defect in the cable. Oil filled cables are favourable in case of long distance power transmission where solid cables are not practical to be used, like in oceans.

Limitations of conventional cables for bulk power transmission is that there are huge eddy current losses and losses due to Joule's heating ( losses).

A company is evaluating suppliers for polyethylene sheaths for a particular type of high-pressure oil-filled submarine power cable. They want to see solid evidence that the true standard deviation of sheath thickness is less than 0.05 mm. (a) Set up the null and alternative hypothesis. (b) Describe a Type 1 and Type 2 error in this situation. Your answer should be in context of the problem.

Describe your design for a transformer that steps up voltage from 120 to 1200 V. (Talk about the numbers of turns and the material of the core, specifically.) Will the input and output be AC or DC electricity (there is only one right answer for this one unless you get fancy)? Compare the input current to the output current (hint: the output power in the secondary coils should be calculated to be the same (actually slightly less, due to inefficiencies)...

DO NOT COPY FROM PREVIOUS SOLUTIONS Design a low-voltage, high-current, shunt-excited DC motor for an industrial facility. The motor should have the following specifications: The output power of the machine is expected to be between (50) hp. The copper losses in the machine should be between 4% and 7% of the output power. The brush losses in the machine should be between 2% and 5% of the copper losses. The no load power should not exceed 6% of the output...

Seastrand Oil Company produces two grades of gasoline: regular and high octane. Both gasolines are produced by blending two types of crude oil. Although both types of crude oil contain the two important ingredients required to produce both gasolines, the percentage of important ingredients in each type of crude oil differs, as does the cost per gallon. The percentage of ingredients A and B in each type of crude oil and the cost per gallon are shown. Crude Oil Cost ...
