the machines running in parallel, the load shouldbe adjusted so that each machine is carrying its proportion. Indirect-current practice, this is done by moving the field rheostatand changing the voltage. However, change of field current on analternator running in parallel wuth another will not do… … O §O ■£c^ s o H SWITCHBOARDS 41 it may be placed on the new machine by governor adjustment.It should be remembered that shifting the field rheostat only causescross currents to flow between machines. The rheostats shouldonly be moved for voltage adjustment and all machines shouldthen be adjusted in…
