Condensers F.7334 - Order No.2061 dated 25.7.19. With reference to Mr.Turner's visit to our Works and interview with our Mr.Bailey re the question of testing Condensers. We have now received instructions from our Technical Department that the Condensers are to be tested as follows before being despatched from your works. Also that a certificate should be given with each Condenser that said test has been carried out and the Condenser has proved satisfactory. 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 each condenser which has past this test will be free from any cause for complaint. Yours faithfully, FOR ROLLS-ROYCE, LTD. | ||
