Transformer ampere rating of the transformer secondary. 2,400 volts, 12 anodes, and anode the d-c load current; b the voltage and kilovolt-ampere rating of each trans- whose primaries are in delta. Assuming an arc drop of 20 volts, calculate a energized from a 4,600-volt three-phase source through a three-phase transformer 33. A three-anode mercury-arc rectifier supplies a 250-kW 230-volt load and is (d the kilovolt-ampere rating of the transformer primary; e) the kilovolt- secondary windings; c the primary current, neglecting the exciting current late: (a) the anode current; (b) the voltage rating of each of the transformer primary of the transformer is connected to a 4,600-volt source, the tube drop is arc recycler has an arc drop of 15 volts and delivers a d-c.
