Some more Q and A for TODAY.
May you all have a BLESSED DAY.

65. Explain the term BOM?

BOM stands for Bill of Materials; it is a list of item or parts that makeup a product assembly. For example, a lawn mower requires a handle assembly, metal deck assembly, a control assembly, motor and blade assembly.

66. Explain what is QMS?

QMS stands for Quality Management System; it documents all necessary information about company’s design and operational controls, including issue reporting, monitoring, continuous improvement and training, to make sure that company delivers continuous product.

67. What is the challenge in manufacturing products?

Main challenge in manufacturing is to develop better production processes, ensure the right material and component supplies at the least cost, decrease production time, eliminate wastage and maintain quality in the final product.

68. Define the term “factory overhead”?

During the manufacturing process, whatever the cost is incurred during the process is referred as “factory overhead”, excluding the cost of materials and direct labors.

69. Explain how to supervise in a manufacturing unit?

Supervising a manufacturing process includes attending to the individual phases of the production. Also, manufacturing supervisor should have a close eye on the inventory that going to be used.
Step 1: Keep the records of different phases of manufacturing also analyse whether the amount of product produced by the crew is enough to meet the demand
Step 2: Look for the bottlenecks in the unit and see how you can eliminate it
Step 3: Keep the track of inventory and try to reduce the liquid capital used after unused material
Step 4: Examine the final goods to determine whether they meet the company’s quality standards.

70. Explain the process of commutation in a dc machine. Explain what are inter-poles and why they are required in a dc machine.

Commutation: It is phenomenon when an armature coil moves under the influence of one pole- pair; it carries constant current in one direction. As the coil moves into the influence of the next pole- pair, the current in it must reverse. This reversal of current in a coil is called commutation. Several coils undergo commutation simultaneously. The reversal of current is opposed by the static coil emf and therefore must be aided in some fashion for smooth current reversal, which otherwise would result in sparking at the brushes. The aiding emf is dynamically induced into the coils undergoing commutation by means of compoles or interpoles, which are series excited by the armature current. These are located in the interpolar region of the main poles and therefore influence the armature coils only when these undergo commutation.

71. Comment on the working principle of operation of a single-phase transformer.

Working principle of operation of a single-phase transformer can be explained as An AC supply passes through the primary winding, a current will start flowing in the primary winding. As a result, the flux is set. This flux is linked with primary and secondary windings. Hence, voltage is induced in both the windings. Now, when the load is connected to the secondary side, the current will start flowing in the load in the secondary winding, resulting in the flow of additional current in the secondary winding. Hence, according to Faraday’s laws of electromagnetic induction, emf will be induced in both the windings. The voltage induced in the primary winding is due to its self-inductance and known as self-induced emf and according to Lenses’ law it will oppose the cause i.e. supply voltage hence called as back emf. The voltage induced in secondary coil is known as mutually induced voltage. Hence, transformer works on the principle of electromagnetic induction.

72. What is rated speed?

At the time of motor taking normal current (rated current) the speed of the motor is called rated speed. It is a speed at which any system take small current and give maximum efficiency.

73. If one lamp connects between two phases it will glow or not?

If the voltage between the two phases is equal to the lamp voltage then the lamp will glow. When the voltage difference is big it will damage the lamp and when the difference is smaller the lamp will glow depending on the type of lamp.

74. What is the full form of KVAR?

We know there are three types of power in Electricals as Active, apparent & reactive. So KVAR is stand for ``Kilo Volt Amps with Reactive component.

75. Two bulbs of 100w and 40w respectively connected in series across a 230v supply which bulb will glow bright and why?

Since two bulbs are in series they will get equal amount of electrical current but as the supply voltage is constant across the bulb (P=V^2/R).So the resistance of 40W bulb is greater and voltage across 40W is more (V=IR) so 40W bulb will glow brighter.
76. Why temperature rise is conducted in bus bars and isolators?
Bus bars and isolators are rated for continuous power flow that means they carry heavy currents which rises their temperature. So it is necessary to test this devices for temperature rise.

77. What is a System?

When a number of elements or components are connected in a sequence to perform a specific function, the group of elements that all constitute a System

78. What is Control System?

In a System the output and inputs are interrelated in such a manner that the output quantity or variable is controlled by input quantity, then such a system is called Control System.
The output quantity is called controlled variable or response and the input quantity is called command signal or excitation.

79. What are different types of Control Systems?

Two major types of Control Systems are 1) Open loop Control System 2) Closed Loop Control Systems
Open loop Control Systems: The Open loop Control System is one in which the Output Quantity has no effect on the Input Quantity. No feedback is present from the output quantity to the input quantity for correction.
Closed Loop Control System: The Closed loop Control System is one in which the feedback is provided from the Output quantity to the input quantity for the correction so as to maintain the desired output of the system.

48. What is the significance of vector grouping in Power Transformers?
Answer:
Every power transformer has a vector group listed by its manufacturer. Fundamentally it tells you the information about how the windings are connected (delta or wye) and the phase difference between the current and voltage. EG. DYN11 means Delta primary, Wye Secondary and the current is at 11 o clock referred to the voltage.

49. Type of A.C motor is used in the fan (ceiling fan, exhaust fan, pedestal fan, bracket fan etc) which are find in the houses?
Answer:
Its Single Phase induction motor which mostly squirrel cage rotor and are capacitor start capacitor run.

50. Why, when birds sit on transmission lines or current wires doesn’t get shock?
Answer:
It’s true that if birds touch the single one line (phase or neutral) they don’t get electrical shock… if birds touch 2 lines than the circuit is closed and they get electrical shock. so if a human touch single one line (phase) then he doesn’t get shock if he is in the air (not touching – standing on the ground if he is standing on the ground then touching the line (phase) he will get a shock because the ground on what we standing is like line (ground bed – like neutral) । and in the most of electric lines the neutral is grounded. So that means that human who touch the line closes the circuit between phase and neutral.

51. What happens if we give 220 volts dc supply to tube light?
Answer:
Bulbs [devices] for AC are designed to operate such that it offers high impedance to AC supply. Normally they have low resistance. When DC supply is applied, due to low resistance, the current through lamp would be so high that it may damage the bulb element.

52. Which motor has high Starting Torque and Staring current DC motor, Induction motor or Synchronous motor?
Answer:
DC Series motor has high starting torque. We cannot start the Induction motor and Synchronous motors on load, but cannot start the DC series motor without load.

53. What is vacuum circuit breaker? Define with cause and where we use it.
Answer:
A breaker is normally used to break a circuit. While breaking the circuit, the contact terminals will be separated. At the time of separation an air gap is formed in between the terminals. Due to existing current flow the air in the gap is ionized and results in the arc. Various mediums are used to quench this arc in respective CB’s. But in VCB the medium is vacuum gas. Since the air in the CB is having vacuum pressure the arc formation is interrupted. VCB’s can be used up to 11kv.

54. What is ACSR cable and where we use it?
Answer:
ACSR means Aluminum conductor steel reinforced, this conductor is used in transmission & distribution.

55. What’s is MARX CIRCUIT?
Answer:
It is used with generators for charging a number of capacitor in parallel and discharging them in series. It is used when voltage required for testing is higher than the available.

56. What is the principle of motor?
Answer:
Whenever a current carrying conductor is placed in a magnetic field it produce turning or twisting movement is called as torque.

57. What is electric traction?
Answer:
Traction means using the electric power for traction system i.e. for railways, trams, trolleys etc. electric traction means use of the electricity for all these. Now a days, magnetic traction is also used for bullet trains. Basically dc motors are used for electric traction systems.

58. How can you start-up the 40w tube lite with 230v AC/DC without using any choke/Coil?
Answer:
It’s possible by means of Electronic choke. Otherwise it’s not possible to ionize the particles in tube. Light, with normal voltage.
What is “pu” in electrical engineering?
Answer:
Pu stands for per unit and this will be used in power system single line diagram there it is like a huge electrical circuit with no of components (generators, transformers, loads) with different ratings (in MVA and KV). To bring all the ratings into common platform we use pu concept in which, in general largest MVA and KV ratings of the component is considered as base values, then all other component ratings will get back into this basis. Those values are called as pu values. (p.u=actual value/base value).

59. Operation carried out in Thermal power station?
Answer:
The water is obtained in the boiler and the coal is burnt so that steam is obtained this steam is allowed to hit the turbine, the turbine which is coupled with the generator generates the electricity.

60. Why link is provided in neutral of an ac circuit and fuse in phase of ac circuit?
Answer:
Link is provided at a Neutral common point in the circuit from which various connection are taken for the individual control circuit and so it is given in a link form to withstand high Amps. But in the case of Fuse in the Phase of AC circuit it is designed such that the fuse rating is calculated for the particular circuit (i.e. load) only. So if any malfunction happen the fuse connected in the particular control circuit alone will blow off.

61. Enlist types of dc generator?
Answer:
D.C. Generators are classified into two types 1)separately excited d.c.generator 2)self-excited d.c.generator, which is further classified into;1)series 2)shunt and 3)compound(which is further classified into cumulative and differential).

62. What is the difference between an Electronic regulator and ordinary rheostat regulator for fans?
Answer:
The difference between the electronic and ordinary regulator is that in electronic reg. power losses are less i.e. for as we decrease the speed the electronic reg. give the power needed for that particular speed but in case of ordinary rh type reg. the power wastage is same for every speed and no power is saved. In electronic regulator triac is employed for speed cntrl.by varying the firing angle speed is controlled but in rheostat ctrl resistance is decreased by steps to achieve speed control.

63. What was the difference between Electrical Engineering and Electronics Engineering?
Answer:
Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics, and electromagnetism. Electronics engineering, or electronic engineering, is an engineering discipline where non-linear and active electrical components such as electron tubes, and semiconductor devices, especially transistors, diodes and integrated circuits, are utilized to design electronic circuits, devices and systems, typically also including passive electrical components and based on printed circuit boards.

64. What is an exciter and how does it work?
Answer:
There are two types of exciters, static exciter and rotary exciter. Purpose of exciter is to supply the excitation dc voltage to the fixed poles of generator. Rotary exciter is an additional small generator mounted on the shaft of main generator. If it is dc generator, it will supply dc to the rotary poles through slip ring and brushes (conventional alternator). if it is an ac exciter, output of ac exciter is rectified by rotating diodes and supply dc to main fixed poles.ac exciter is the ac generator whose field winding are stationary and armature rotates. Initial voltage is built up by residual magnetism. It gives the starting torque to the generator.
