About this document
Power System Voltage Clearance Standards by marab12 is a document available to read on EtoBox.
This document provides minimum clearance distances for different voltage levels of power systems. It lists the nominal system voltage, highest system voltage, withstand voltage at 50 Hz for 1 minute, and lightning impulse voltage for various voltage levels. It then gives the minimum clearances in millimeters required between phases and earth and between phases. The document concludes by specifying standard clearance distances for different voltage levels for things like height of conductors above walkways a
