A connection device includes a body having a first and a second end, a first connector set at the first end, and a pin type connector set at the second end. The first connector set includes a first strip element and a second strip element, which form an electrical interface of the connection device. The pin type connector set includes a first element and a second element, and thus forms another electrical interface of the connection device, different from the electrical interface formed by the first connector set. The pin type connector may be projecting pins or hollows that receive pins. The first connector set is electrically connected to the pin type connector set. Thus, the connection device is adapted for electrically connecting a generator with an exciter having incompatible electrical interfaces.
