Which of the following most accurately describes the problem?

the plant was installed by the Parsons Motor Co., Ltd., Town Quay, Southampton. The Parsons engine employed for driving the dynamo and exciter comprises a six-cylinder unit capable of developing 42 b.h.p., the governing of which, owing to the nature of the work, has to be within about 5 per cent. When the are is struck, the full load comes on immediately, and when the arc is broken the whole load is suddenly thrown off, so that it will be seen that the conditions of operation are particularly strenuous,'aod called for first-class engine work on the part of The Parsons Motor (3e.; td. In addition to this rapid variation of power 6utput, the whole of such a plant has to be capable of running many hours together at full power if it be engaged on a long job.
