Deepakkumar Yadav Power Factor Tariff Results into Energy Conservation Q. Discuss how power factor tariff results into energy conservation. Solution : Power factor tariff results into energy conservation : Applying incentives and penalties according to power factor is an effective way, which enables consumer to improve power factor so that he can reduce his higher electricity bill. … Read more
Terms Involved in Tariff 1. Variable load : The load on a power station varies from time to time due to uncertain demands of the consumers and is called as variable load. An ideal load is one which is always constant for a given duration of time. However, ideal load can be realized in practice. … Read more
Importance and purpose of Earthing Q. Explain importance and purpose of earthing. To save human life from shock due to current leakage of installation. To protect large buildings from lightening fall. To isolate the faulty section. This is achieved by providing path of leakage current through earthing system at this instant protective gearing operates. To … Read more
Energy Audit Instruments And Their Uses Q. Explain following energy audit instruments and their use. The requirement for an energy audit such as identification and quantification of energy necessitates measurement these measurements required the use of instruments. These instruments must be portable, durable, easy to operate and relatively inexpensive. An energy audit requires a large … Read more
Industrial End User (Electrical Distribution System) At the industrial end user premises, again the plant network elements like transformers at receiving sub-station, switchgear, lines and cables, load break switches, capacitors, cause losses, which affect the input-received energy. However the losses in such systems are meager and unavoidable. A typical plant (single line diagram) of electrical … Read more
Advantages of Intelligent Power Factor Controller for the Improvement of Energy Efficiency Increase in system voltage can be avoided with it. Capacitor’s life increases. Plant efficiency increases. Utilization of demand is optimized. Line losses are reduced. Extra load can be connected without sanction of additional demand. Demand penalty can be avoided. Zero cost maintenance is … Read more
Power Factor Correction As studied earlier, induction motors are characterized by power factors less than unity, leading to lower overall efficiency (and higher overall operating cost) associated with a plant’s electrical system. Capacitors connected in parallel (shunted) with the motor are typically used to improve the power factor. The impacts of p.f. correction include reduced … Read more
Specific Electrical Tariffs 1. Power factor incentives : Incentive is given to those consumers who are charged on the basis of maximum demand and are provided with meters to measure their load power factor. When the average power factor of the consumer is more than 0.95 an incentive at the rate of 1% of the … Read more
Types and Classification of Cogeneration Systems Q. Give Classification of Co-generation system on the basis of sequence of use and use of technology. This classification is based on different criteria Symbols Used : 1. Turbine unit similar to this symbol of compressor. It has rotary blades on the shaft and input energy is impinged on … Read more
Energy Conservation Techniques In Transformer Q. State energy conservation techniques in transformer. (A) Load Sharing : The problems like overloading, variation in voltage and heating are very common in transformers. . It takes a lot of time for its repairing and maintenance and also involves high cost Load sharing protects the transformer under overload condition. … Read more
