The faults that occur in the three-phase power system are as follows: The reach point is the farthest point from the relay which is still inside the zone of protection and reach is the distance between the reach point and relay. Anyone can do that. In resistance grounding, one or more resistance is connected to the neutral of the system. Keep it mostly work and career related. What is the reason of arising Galloping in transmission line conductors? One is that it is designed to make sure a computer system performs well by managing its computational activities. The generation, distribution, and transmission system together constitute a network called as Power plant. Where the value of surface irregularity factor μ for a different surface condition is as follows: A slack bus also known as reference bus or swing bus balances the active and reactive power of the system. if it is greater than 1 then load will act as capacitor and starts feeding the source and will cause tripping. Control system interview questions and answers. 3 0 obj Please mail your requirement at hr@javatpoint.com. Resistance winding limits the fault current and protects the system from transient overvoltages. interrupts the powers supply and damages the damages the electrical installations. either by direct strokes on the equipment or by the strokes on the transmission lines that reach the equipment as travelling waves. Reference: WomenCo. Depending upon the voltage and length of the conductor the classification of the transmission line is as follows: The Relay is an automatic device that senses the abnormal condition of the electrical circuit and closes its contact. RLDC, SLDC, NLDC 6. The value of power factor will always be less than 1.

The protection is organized to provide a ring of security around each and every element of power system. If any fault occurs in the system then the relays associated with it trip all the circuit breaker so that the faulty element gets removed from the power system. SCADA is a type of software application and hardware control that defines the way data and real-time processing is controlled.You mostly find SCADA in every industries such as power plants and oil and refining … sanfoundry.com Electric Circuits Interview Questions and Answers by Manish 3 minutes This set of Electric Circuits Interview Questions and Answers focuses on “The International System of Units, Voltage and Current, Power and Energy”. I am very self-motivated. The difference between the relay and the circuit breaker is that relay is a switching device that gives the signal to the circuit breaker in case of fault occurrence, whereas circuit breaker breaks the circuit automatically when receives the signal. Earthing is important because of the given below reasons: 'Sag' is the difference in level between the points of support and the lowest point on the conductor. x��Z[o��~7���O9$`�y'U-��i]�nҨ�C���l�4�J��ǟ�fy���؃ �$�����/.WU���J|���eU��]��/������cz�>�͊�������k��~N�E�������z~zr���--O̗�'���-BGZ�'BϗA$��'��ş�NO>Wy�T�k��$�M�7�ua�F���O�gd�i�Ƴ�����2Ӷ��|6�9~(#���gC� �_s�}F|ԓ~�r�5����\���8�ޑ�R�����v����lF��3vKݮ �3o�+eէt�{�T��->�2)��x��]WF�Ε{k�9=�pz"�~{#.4�����Ao��ʲ��������>�=nߒ9�����T'>�re8�nk�Τ�s��5_`Ν����!���\�V}���wΈ{S~��1_ K���♝�׫7d If it is too low then cable over heating & equipment overloading will occur. stream What is meant by synchronous condenser? Operating systems exist for two main purposes. Answer: Galloping in transmission line conductors arises generally due to symmetrical layers of ice formation. The difference between Fuse and a circuit breaker is that fuse works on the principle of the thermal and electrical properties of the conducting materials, whereas the circuit breaker works on the principle of electromagnetism and switching principle. Q.1. For removing the faults the entire circuits connecting the faulty section needs to be open. All rights reserved. Lifestyle Digest, updates@m.womenco.com 1. Earthing protects the persons and apparatus from the high voltage surges and lightning discharge. Duration: 1 week to 2 week. <> The existing weather conditions like lightning strikes, heavy rains, heavy winds, salt deposition on overhead lines and conductors etc. Power System Interview Questions. 1) Explain the main purpose of an operating system? <>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/StructParents 0>> A list of top frequently asked Power System interview questions and answers are given below.
