Rm{William Robotham - Chief Engineer}/CAP.11/WH.28.10.37. LUCAS DYNAMO REGULATOR AND CUTOUT. The Lucas regulator and cutout, are mounted on one base, together with the necessary terminals, thus forming one unit. A number of these units was recently submitted by the makers for our approval; tests on these are now completed. In investigating these units our main considerations have been:- (1) Suitability of performance characteristics. (2) Reliability, i.e. ability to maintain performance, and freedom from breakdown. (3) Reasonable length of life. Although this type is likely to be cheaper than the present standard, the question of price is for the time being, ignored; as it is more a matter of finding a regulator that is really reliable, than finding the cheapest good one. Regulators. (1) Performance Characteristics. Hitherto we have always tested regulators with respect to:- (a) Dynamo open circuit, at speeds up to 6,000 r.p.m. (b) Output current under night-running conditions, at all regulating speeds. (c) Output current under day-running conditions, at all regulating speeds. (d) The extent, and effect of rise in temperature of the unit. continued. | ||
