摘要：
Some operating characteristics of electrically driven, center-pivot irrigation machines were measured in the field. Peak power demands over fractional-minute periods were about twice the average demand. Power factors for the machines ranged between 0. 3 and 0. 5, and at least 1 kVA per connected hp was necessary to meet average electrical demands. Results from these tests are presented.
