     Electrical Substations An electrical substation forms an integral part of the power system. It is placed at the both ends of the long distant transmission line... but why??!! Of-course to transform voltage!  A substation at the beginning End or say generation side normally used to boost up the voltage to higher magnitude suitable for transmitting the generated power to long distant load with minimum losses.( Uses a step up transformer )!! Yes the other type is at the other end of the long distant transmission line nearer to load centre... here the high voltage is stepped down to a relevant magnitude which may be used for distribution purpose or another voltage level transmission for near by substations.                    The heart of a substation is nothing but our transformer, depending upon the purpose transformer can be step up or step down!! Now we are considering a load end substation as an example. Here our hero is step down transformer 😎!! A substation h

Ever wondered why there an extra line on top of every transmission line we see.? Ever thought why we use any insulators for that line.? One among the level of protection for the power system is this Earth / Shield wire. As for the power system(OH Line), biggest enemy is the lightning surge. Even though we install arrestors, it solely cannot complete the work. For increased rate of protection we use earth wire on top of the transmission line. The overhead earth wire or ground wire is the form of lightning protection using a conductor or conductors. It is attached from support to support above the   transmission line   and well grounded at regular interval. The earth wire intercepts the direct lightning strikes, which would strike the phase conductors. The ground wire has no effect on switching surges. When the lightning strikes an earth wire at mid-span, waves are produced which travel in opposite directions along the line. The waves reach the adjoining tower, which pass

   How do we control mechanical vibrations generally, yeah by some sort of vibration absorbing techniques.Then, what about the vibrations present on transmission lines ? Well that's indeed a  question. It isn't the rocket science, just a matter of transferring and or dissipating the energy behind it. Lets see how it is engineered.    As the wind passes some of its energy gets transferred to the overhead transmission lines and tends to oscillation(mostly).But as the weight of the conductor is high to limit the oscillation the energy try to get converted to the form of vibration.Vibrations then spread across the conductor length and its not a good thing in mechanical aspects as its causes the deterioration of strength of conductors.In engineering view of thinking it is only avoided by absorbing the energy causing it.The simple way for it is damping those vibrations mechanically from the line itself, that particular concept resulted in the designing of vibration dampers.
