Shunt capacitor switching can inject high magnitude, high frequency current transients into the substation ground grid. These current transients produce step and touch potentials that can affect personnel safety. In order to assess the hazards of such switching, measurements of transient step and touch potentials caused by shunt capacitor switching were made at BPA's 500-kV Ostrander Substation near Oregon City, Oregon. The testing was focused on whether or not it is safe for personnel to work… CONTINUE READING
