What is the main objective of protection?
The objective of protection is to remove only the affected portion of plant and nothing else.
A circuit breaker or protection relay may fail to operate.
In important systems, a failure of primary protection will usually result in the operation of back-up protection..
What do you understand by zone of protection?
“Zones of protection” is one strategy that can be used to provide the level of security demanded today. Protective relay engineers keep utility grids and equipment safe from faults and system unbalances by dividing the grid into zones, each with a unique protection scheme. Overlapping zones provide backup protection.
What is aims and objectives of consumer protection act?
The main objective of the Consumer Protection Act, 1986 is to protect the interests of consumers in India. It aims to provide a speedy and simple redressal to consumers’ grievances. It provides effective safeguards to consumers against various types of exploitations and unfair trade practices.
What is the aim of the Consumer Protection Act?
What is the aim of the Consumer Protection Act? The basic aim of the Consumer Protection Act, 2019 to save the rights of the consumers by establishing authorities for timely and effective administration and settlement of consumers’ disputes.
Why backup protection is necessary?
The backup protection provides the back up to the main protection whenever it fails in operation or its cut out for repairs. The backup protection is essential for the proper working of the electrical system.
How can I protect my transmission line?
Overcurrent and Earth-Fault Protection of Transmission Lines: The general practice is to employ a set of two or three overcurrent relays for protection against phase-to-phase faults and a separate overcurrent relay for single line-to-ground faults.
What is the major cause of the failure of the circuit breaker?
Power Surges and Spikes A common occurrence in electrical components, voltage surges and spikes often cause an electrical circuit breaker to fail. However, the chances of circuit breaker failure can be minimized by equipping the electrical panel with a surge suppressor.
What is overcurrent protection?
An overcurrent protection device protects the circuit by opening the device when the current reaches a value that will cause an excessive or dangerous temperature rise in conductors. Most overcurrent protection devices respond to both, short-circuit or ground-fault current values as well as overload conditions.
What is distance protection of transmission lines?
Distance Protection is a Non-unit System of Protection, which measures the Impedance between the Relay Location and the point where the fault is incident and compares it with the Set Value. If the measured Impedance is less than the Set Value , the Relay operates and Isolates the Faulty Section.
What are the functions of protective relays?
The purpose of the protection relay is to detect a problem, ideally during its initial stage, and to either eliminate or significantly reduce damage to personnel and/or equipment.
Why is protection necessary in power?
The main objective of using power system protection is to detach the faulty section from the system to make the rest of the portion work without any disturbance. In addition to this, it is used for the protection of power system and prevent the flow of fault current.
Why is transmission protection important?
As you already know, the real purpose of transmission line protection is to detect faults or abnormal operating conditions and to initiate corrective action. Protective relays must be able to evaluate a lot of parameters to choose and establish right corrective action.
Why do we need protective relaying in the power system?
Relays detect and locate faults by measuring electrical quantities in the power system which are different during normal and intolerable conditions. The most important role of protective relaying is to first protect individuals, and second to protect equipment.
What are the objectives of consumer?
Objectives of and Basis for the Consumer Rights The objective of the consumer rights is to protect the consumers. Individuals are seen to require protection when acquiring products or services for their own personal use.
Which type of relay is applicable for AC?
Induction Type RelaysInduction Type Relays These are used as protective relays in AC systems alone and are usable with DC systems. The actuating force for contacts movement is developed by a moving conductor that may be a disc or a cup, through the interaction of electromagnetic fluxes due to fault currents.
