Cooper Power Systems 50 A externally operated single-phase under-oil series multiple switches are used to connect primary windings either in series for a higher winding ratio, or parallel for a lower winding ratio. This versatility allows one transformer to be stocked that can be used at either of two system voltages. This minimizes inventory and eases voltage conversion. Time-consuming manual voltage changeovers inside the transformer tank are also eliminated. The 50 A switches may be used for 2:1 or lower voltage ratios only.
