Voltage Control Methods of Transmission Line And Distribution Line

Voltage Control Methods of Transmission Line And Distribution Line (a) By Transformer Tap changing : Transformer tap changing is the basic and earliest way in various transmission, sub transmission and distribution. In high voltage or extra high voltage lines on load tap changing (OLTC) transformers are used while off-load tap changers are used in distribution … Read more

Energy Flow Diagram, Converting Electrical Energy to Heat to Light

Energy Flow Diagram, Converting Electrical  Energy to Heat to Light Take the case of a filament lamp ( which was used in early days because now a days these are replaced by LEDs ). Such diagrams are very simple, input-losses output. These diagrams are developed by a scientist “Sankey”, so these diagrams are also called as Sankey diagrams. … Read more

Energy Conservation

Energy Conservation Energy conservation means using energy more efficiently and less wastage of energy. The most important aspect in this connection is that the energy conservation plan should try to eliminate wastage of energy at every step of production, conversion, without affecting the productivity and growth rate. Energy conservation requires new on going investments, more … Read more

Types of Energy Audit

Types of Energy Audit The energy conservation opportunities may be easily identifiable or may be identified only after intermediate study or detailed study. The energy audits are classified into three types : Simple Walk – through energy audit. Intermediate energy audit. Comprehensive (Exhaustive) energy audit. The general remarks are as under. Types of Energy Audit … Read more
