Institute of Engineering • 2082 Chaitra Board Examination
Q1[1 Marks]High Voltage AC (HVAC) Transmission Characteristics
For each of the following statements, state whether it is TRUE or FALSE and provide brief justification for your answer. a) Lightning Arrestor (LA) rating of overhead transmission line is independent of the system neutral grounding condition. [1+3] b) Conductor to conductor vertical spacing at a transmission line tower depends on the conductor swinging due to wind force. [1+3] c) The effective way to increase corona inception voltage is to increase the conductor size. [1+3] d) The simulation method of load forecasting is more suitable for a small area load forecast.
Q2[4 Marks]High Voltage AC (HVAC) Transmission Characteristics
(a) What are the advantages and disadvantages of interconnected system? [4] (b) Discuss the economic and technical criterion to be considered while selecting the size of the standard voltage level and number of circuits for transmission line design. [8] (c) Show that for EHV transmission line, use of double earth wires can reduce the tower height.
Q3[8 Marks]High Voltage AC (HVAC) Transmission Characteristics
a) Derive the expression relating conductor tension to temperature for an overhead transmission line including the effects of elastic extension. [6] b) An overhead transmission line uses a "Lion" ACSR conductor with a span of 300 m and supports at the same level. The conductor is subjected to two loading conditions as given in the table below. Determine the horizontal tension in the conductor under the easiest condition.
Conditiontemperatureice thicknesswind pressurehorizontal tension
Toughest conditionFactor of safety 2 from UTS
Easiest conditionNo iceNo wind?
Consider the following: Ice density: Conductor modulus of elasticity: Conductor coefficient of linear expansion: Refer Conductor table for other relevant data
Q4[8 Marks]Voltage Drop and Power Loss in Distribution Systems
a) Compare the following with the necessary diagram: [2x4] (i) Radial and Loop distribution system. (ii) American and European distribution system. b) Two distribution load centers operate at the same voltage level and supply the same total load, but their low-tension (LT) line configurations differ as follows: Load Center 1: 4 LT feeders, each of 1 km Load Center 2: 2 LT feeders, each of 2 km Assuming the load is uniformly distributed along the feeders and same conductors for all feeders, compute the ratio of the percentage power losses in the LT lines of Load Centre 1 to that of Load Centre 2.
Q5[6 Marks]Voltage Drop and Power Loss in Distribution Systems
a) How does consumer classification affect load forecasting in distribution systems? [4] b) A daily load pattern of a particular load center is given in table. Calculate, [8] (i) daily loss of load factor (ii) if % peak power loss is 7%, determine the % energy loss.
Time (hr)0-66-1010-1818-2222-24
Demand (p.u)0.20.50.210.2
c) Discuss the criteria and procedure for selecting the location, capacity, and primary voltage of a distribution transformer in a distribution system.
