Abstract :
Part I is an introduction, showing the need for reliable records of power disturbances in transmission lines, and showing that the incandescent-lamp oscillograph is the only practicable recorder of such chance disturbances. Part II describes the Power Osiso which is a very compact and highly efficient oscillograph, having an instantaneous wattmeter, a permanent-magnet galvanometer, and a relay arrangement with control for automatic operation on chance disturbances. The various auxiliary apparatts, such as daylight-loading film holders, 6-volt motor, potential circuit control, etc., is also described, together with different connections for the same. Part III describes the Multi-Element Oscillograph, which gives from 3 to 9 simultaneous records on one film, also the various auxiliary apparatus and the possible combinations thereof. A detailed description is given of the automatic operation equipment and its action in recording chance disturbances.
