Post: A good guide For 'exported PME' and outbuildings!Same as my last report, ....but to inform that it is not just 1 post but 4 of them from post 33 to 36....

You willget this on Drawings . Apprentices . - Service Cable : The service conductors made up in the form ofa cable . - Service Conductors : Thesupply conductors that extend from the Street Main or Transformers to theService equipment of the premises being supplied .
-Surge : (1)A sudden increase in voltage & current (2) Transient condition . - Starter : An electric controller for accelerating amotor from Rest to NormalSpeed & for stopping the motor . - Starting Winding :Winding in an electric motor used only during the brief period when the motoris starting .
DoNot mix up the twoWords . - Stator/ Starter . ◄◄ - Stator :The portion of a rotating machine that includes & supports the stationary ActiveParts . * Volt :The practical unit of voltage of electromotive force . One volt sends a currentof One ampere through a résistance of One ohm . * Voltage: Voltage is the force . pressure . or electromotive force ( emf ) that causes electriccurrent to flow in an electric circuit . its unit of measurement is the Volt .which represents the amount of electrical pressure that causes current to flowat the rate of One Ampere through a résistance of One ohm . Voltage in anelectric circuit is often considered similar to Water pressure in a pipe orwater system . * Voltage Drop( Vd ) The voltage drop in an electrical circuit is difference between thevoltage at the power source & the voltage at the point at which electricityis to be used The voltage drop ( Loss ) is created by the résistance of theconnecting conductors . * Watt : Theunit of measurement of electrical power or rate of Work ( 756 Watt ) isequivalent to ( 1 hp ) The Watt represents the rate at which power is expendedwhen a pressure of ( 1V ) causes current to flow at a rate of ( 1A ) in a D.C.circuit or in A.C. circuit at Unity ( 100% ) power factor . The number of Watts equals the pressure ( in Volts ) multiplied by thecurrent ( in Amperes )
