To simplify the Mulvany DCVG coating fault location, the applied CP is separated from all other DC influences--such as Tellurics and DC Traction--by pulsing the CP rectifiers at approximately one hertz.
However, this is impossible because there are significant influences such as DC Traction, Tellurics, and Long Line Currents that cannot be switched.
