A two wire DC distributor AB, 1000 meter long, is supplied from both ends, 240 V at A and 242 V at B. There is a concentrated load of 200 A at a distance of 400 meter from A and a uniformly load 1.0 A/m between the midpoint and end B. Determine (i) the current fed at points A and B (ii) the point of minimum potential and (iii) voltage and this point. Consider cable resistance as 0.005 ohm per 1000 meter each core.

Substations have the functions of: Transmission Elevator, Subtransmission Lower and Distribution, according to their purpose. The common characteristic of the types presented is their objective, which is to modify the characteristics of electrical energy. Substations have sets of conductors, equipment and devices, and with these sets they work to ensure performance and safety in the electrical distribution system. Substations are also responsible for switching, protection, voltage and current transformation, reactive compensation to direct the power flow and enable its diversification through alternative routes, or a combination of these in the Electric Power System (SEP) . Describe the role of substations in the distribution of electricity, and what is their relationship with the primary and secondary distribution, describing the consumers of these demanded loads. PLEASE TYPEABLE BECAUSE THE LETTERS GET IN THE UNDERSTANDING.

As an Engineer you have been contracted by a power distribution company to investigate the causes of frequent transformer failures in its network. In the course of your investigation you came across the following: The Transformer installed in urban area failed within the warrant period of 3 years; the diagnostic results showed failure of one phase of the High Voltage (HV), It was further observed that this failure was causes by Overheating and overloading of that phase which caused burning of both HV and Low Voltage (LV). Explain what could be the cause(s) of this overload and the implications it could have on other equipment in the Transformer

Basic Electrical Engineering You have been sent to a new home. The homeowner reports that sometimes the electric furnace trips the 240-V, 60-A circuit breaker connected to it. Upon examination, you find that the furnace contains three 5000-W heating elements designed to turn on in stages. For example, when the thermostat calls for heat, the first 5000-W unit turns on. After some period of time, the second unit will turn on, and then, after another time delay, the third unit will turn on. What do you think the problem is, and so would your recommendation for correcting? Explain your answer.
