That is, the equipotential bonding line. It is not a loop conductor, it has a protective tie line and a functional link line. They are electrically connected in parallel with the PE line, but because it is far from the phase line, the fault current is shunted little when a ground fault occurs. Therefore, it can only transfer the potential and cannot transmit the fault current. The protective connection line transmits the power frequency potential, which only requires the resistance of the coupling system to be as small as possible. The functional connection line for information technology systems delivers high frequency potentials, which require that the impedance including the reactance within the coupling system be as small as possible.
