What happens to voltage during a fault?
Faults cause voltage to collapse and current to increase. Fault voltage and current magnitude depend on several factors, including source strength, location of fault, type of fault, system conditions, etc.
What causes power in an electric generator *?
An electric generator is a device that converts mechanical energy obtained from an external source into electrical energy as the output. Faraday discovered that the above flow of electric charges could be induced by moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field.
Why does fault occur in power system?
The faults in the power system may occur because of the number of natural disturbances like lightning, high-speed winds, earthquake, etc. It may also occur because of some accidents like falling off a tree, vehicle colliding, with supporting structure, aeroplane crashing, etc.
What are the effects of fault?
One of the main effects of the faults on topography is that they very often result in the development of distinct types of steep slopes which are aptly called fault scarps. Faults are also known to cause deflection in the course of streams.
What do you mean by fault in power system classify it?
Faults in overhead transmission system can be classified into two types, i.e. series (open conductor) faults, and shunt (short circuit) faults. Series faults can be identified easily by observing the each phase voltage. Short circuit faults are divided into two types, i.e. asymmetrical faults, and symmetrical faults.
What causes generator under voltage?
Undervoltage conditions are usually be caused by undersized or overloaded utility and facility transformers. During peak demand periods and/or when the utility is experiencing problems, the demand for power exceeds the capability of the transformer and as a result the voltage drops.
How do faults generate earthquakes?
Faults are blocks of earth’s crust that meet together. Earthquakes occur when rock shifts or slips along fault lines Earthquakes generate waves that travel through the earth’s surface. These waves are what is felt and cause damage around the epicenter of the earthquake.
