rent. The condenser pressure,when the condenser is discharged being zero, the current enters 1,086 HAWKINS ELECTRICITY at maximum velocity as at -4 in fig. 1,327, and gradually de-creases to zero as the condenser pressure rises to maximum at B,this change taking place in one-quarter period. Thus… … CAPACITY PRESSURE90° BEHIND THE CURRENT Fig. 1.328.—Current and pressure curves, showing phase relation between the current, con-denser pressure, and impressed or capacity pressure necessary to overcome the condenserpressure. The capacity pressure, since it must overcome the condenser pressure,…
