Railway Eliminate/Reduce Electrostatic induction

Railway Eliminate/Reduce Electrostatic induction, Screening due to Induced Currents in Rails, Rail reduction factor – Screening due to Return currents through rails, Cable Screening Factor: Due to use of Screened cable, Other Screening Effects Eliminate/Reduce Electrostatic induction Electrostatic voltage falls steeply as the distance of separation increases. It would therefore be desirable to shift the overhead alignments as […]
