Abstract:
1. An engine generator set comprising: an electrical generator configured to provide electrical energy to a first load rated at a first voltage and a first frequency, and to provide electrical energy to a second load rated at a second voltage and a second frequency wherein at least one of the second voltage is different than the first voltage and the second frequency is different than the first frequency; a prime mover rotatably coupled to said generator through a shaft, said prime mover configured to rotate said shaft at a first rotational speed when said electrical generator is generating electrical energy at the first frequency and to rotate at a second rotational speed when said electrical generator is generating electrical energy at the second frequency; an engine generator set control system comprising: an electric motor supplied with electrical power from the output of said electrical generator through a motor protection circuit that includes at least one of an overload and a trip unit communicatively coupled to said output selector such that a trip setting of the at least one of an overload and a trip unit is modified by operation of the output selector.
