[Class 38 (iv).] This Specification, which does not admit of satisfactory abridgment, relates to the transmission of power between interconnected networks. The governors of the prime movers are so controlled upon a change in load on the networks that a " permanent deviation " in the transmitted power is first established and subsequently this deviation is annulled by slow governor adjustment. This secured operation may be employed to reduce the transmitted power to zero for the purpose of disconnecting the line. The Specification describes an automatic system of control dependent upon impulses representative of network loads.
