| X.4589 EFC/T29.1.24. X.4589 - B.L.I.C. VOLTAGE REGULATOR APPLIED TO R.R. 20 HP. DYNAMO. (1) Confirm correct direction of rotation for excitation. (2) Determine polarity of excitation. (3) Determine characteristics of machine without regulator with brush position as set by B.L.I.C. (4) Determine cold and hot open circuit volt-speed characteristics with makers polarity; observe field circuit and regulator cell currents. (5) Confirm cold and hot open circuit volt-speed characteristics with our polarity, taking field and regulator cell currents. (6) Take volt-speed characteristics with our polarity for 1/3, 2/3 and full external conductance corresponding to full load. Observe field, regulator cell and load currents. EFC. | ||
