3 - (a) During the winter heating season of 180 days an office is heated continuously for 10 hours a day by a 3kW electric heater. Assuming the heater is only used during the heating season determine how many gigajoules and kilowatt hours are consumed by the heater annually. (b) Calculate the available power for two hydro schemes. One of the scheme has a flow rate of 3.4 litres/second. And the other is a large river with a flow of 100 m² / second. Both have an effective head which is 80% of the actual head. The actual head is 125m for each. And the plant efficiency is 83% for each.

Question 2.) Give a brief explanation a.) When a live conductor of public electric supply breaks down and touches the earth what will happen? b.) Which equipment should be installed by the consumers having low power factor? c.) Which devices may be used to protect against lightning overvoltages?
The maximum demand of a power station is 110 MW. It generates 105 x 10 units during the day. The station has three units of 40 MW and another unit of 40 MW as spare. The running hours of the unit are as follows. The first unit of 40 MW runs for 24 hours. Another unit of 40 MW runs for 14 hours. A third unit of 40 MW runs for 4 hours. So Find (1) daily load factor (2) plant capacity factor (3) utilization factor and (4) plant use factor.
It is the ratio of the units of electricity generated per year to the capacity of the plant installed in the station ratio of the duration during which the plant is in actual service to the total duration of the period of time considered ratio of the average load to the peak load during a certain prescribed period ratio of the average load on a machine or equipment to the rating of the machine or equipment, for a certain period of time considered Ratio of maximum demand of the plant to the rated capacity of the plant
