What is Soft Starter & Advantages of Soft Starter Q. State four advantages of soft starter When starting, AC induction motor develops high torque than its required value at full speed. This mechanical stress is transferred to the mechanical transmission system resulting in excessive wear-tear and premature failure of chains, belts, gears, etc. Additionally, sudden rise … Read more
Optimizing Distribution Voltage To Reduce Technical Losses The drop of voltage is design consideration for the distributors the feeder size is based on the current carrying capacity of the conductor. In transmission systems, a voltage regulation of as much as 40%, in some cases be considered satisfactory. We are interested in the most economical method … Read more
Reducing Technical Losses by Reducing I2R Losses in Transmission and Distribution System Q. State any four causes of technical losses in transmission and distribution system. The I2R or copper losses of transmission and distribution system can be reduced (conserved) by the following means : Transmitting electricity at high voltage reduces the value of current and hence … Read more
By Compensating Reactive Power Flow (For Reducing Technical Losses) Q. Explain energy conservation in transmission and distribution system by using compensating reactive power. An overhead line, when loaded fully, absorbs reactive power given by (I2x) where, I is the line current and X is the reactance of the line in ohms per phase. On light … Read more
