Abstract
A wind turbine rotor blade portion has a root end, a tip end and a blade shell that defines a suction side, pressure side, leading edge, and a trailing edge of the blade portion. The blade shell includes a lightning conductor including a first conductive material, and at least one spar cap associated with the blade shell and including a second conductive material different than the first conductive material. An equipotential bonding element electrically bonds the lightning conductor to the spar cap. The equipotential bonding element includes a first end portion having a first metallic material adjacent the first conductive material of the lightning conductor, a second end portion opposite the first end portion and having a second metallic material adjacent the second conductive material of the spar cap, and an intermediate portion where the first metallic material is joined to the second metallic material at a joint and having an insulator encapsulating the joint for preventing exposure of the joint to an electrolyte material.
