Power-factor sentence example
When the service is frequent enough to give a good power factor continuously, the steam locomotive cannot compete with the electric motor for the purpose of quick acceleration, because the motors applied to the axles of a train may for a short time absorb power from the central station to an extent far in excess of anything which a locomotive boiler can supply.
The power factor can be improved by decreasing the tank capacitance.
The graph above shows the effect of using offset electrodes on the power factor of the system.
One provides zero volt switching for single-phase resistive loads or for motors where the power factor is greater than 0.8.Advertisement
