In order to decrease the disturbance from a cable testing equipment, the company Ericsson Network Technologies in Falun determined to design a new series resonant test system with a lower frequency. The new equipment is of series resonant type with a system frequency of 500 Hz. This equipment consists of an inductor, a capacitor and a voltage source. The voltage source is the same as the old one, the cable acts as the capacitor but the inductor has to be designed especially for the new equipment. In this thesis work several air coil inductor types were examined. The conclusion is if that a Brooks type inductor yields the highest induction per meter of wire. The cost of this type that fulfill the demands that Ericsson Network Technologies requires is around 200000 SEK if Ericsson uses its own wire.
