【 摘 要 】

The paper analyzes the influence of power tools operating mode on the power quality, especially on the harmonic pollution. The measurements were carried out with the CA 8334B three-phase portable AC power quality analyzer. The low utilization factor of power tools (due to the short duration of operations) introduces complexity in the study of their impact on power quality. Although the absorbed powers are small, the cumulative effect produced by a large number of power tools can be substantial.
