| To O.O. from EFC. X 2512 EFC1/T1.8.19. X.2512 RE CONDENSERS MADE FOR US BY THE G.E.C. X 1627 We consider that the electrical requirements of the condenser produced for us by the G.E.C. to arrangement drg. N.856 should be as follows:- 1. Each condenser should have a capacity in microfarads lying between the limits .19 and .23. 2. Each condenser should have applied to it for a period of 30 minutes, an alternating voltage of 500 (R.M.S value) without failure. We are confident that if the condensers satisfy the above requirements, the possibility of breakdown on the road will be practically negligible. EFC. | ||
