SCADA(supervisory control and Data Acquisition) SCADA is an industrial control system which is used in many modern industries like energy,manufacturing power,water transportation etc.SCADA software receives the info form (PLCs) or remote terminal unit (RTUs) which in-turn receive their info from the sensors or inputted value which we have given manually. SCADA refers to supervisory control … Read more
The generated electrical energy is distributed form the urban areas and delivered to the ultimate consumers through a network of transmission and distribution.There may be the variation of voltage at the consumers terminal which may cause erratic operation or even malfunctioning of the consumers appliances such as motors,lamps and other load.The main cause of the … Read more
Faults in Power system A fault in an electrical equipment’s/apparatus is defined as a defect in the electrical circuit due to which current is diverted from the intended path. It is also defined as the abnormal condition which cause a reduction in the basic insulation strength between phase conductors or between phase conductors and earth … Read more
CONDUCTOR MATERIAL Conductor is one of the important material in a transmission and distribution of electric power.so the proper choice of conductor material and size of the conductor is important. The cost of the conductor material accounts for a major part of the total cost. Requirements of conductor: To transmit power over required distance … Read more
Introduction In the earlier stage dc system was employed for generation,transmission and distribution of the electric power.with the introduction of transformers and 3 phase ac system the electric power generation,transmission and distribution is shifted towards ac system.The first 110V dc central Electric station was installed by Edision in New york in 1882.mercury arc converters were … Read more
Pic source:Power line magazine The insulators are the supporting structures in order to prevent the current leakage to the earth.Mainly the overhead line conductors are bare and not covered with any insulating coating,thus the line conductor are therefore secured with the insulators.Insulator are mounted on the cross arms and the line conductors are attached … Read more
The transmission power lines will enter a distribution substation where the voltage will be stepped down to distribution levels where it will be distributed for use by industrial, commercial and residential customer. At these load points(industrial, commercial and residential customers), a transformer further reduces the voltage from 11 kV to 400 V to provide the … Read more
Distribution system The system which deliver power to electrical consumers at their place of consumption(in customer location and capacity to meet the customer peak demand and energy demand) for local use in reliably usable form(stable voltage quality,higher reliability) is distribution system.Distribution system is the bridge between the transmission system and the consumers meters. Transmission and … Read more
For the economic development of any country power is the basic need. The availability of electricity has been the most powerful tools to drive the economic and social change through the world. Improvement in the standard of living of the people, increase in the productivity in industry, agriculture basically depends upon the adequate supply of … Read more
