【 摘 要 】

Nowadays, virtually everywhere worldwide, the electricity is paid for based on active and reactive power meters. Higher harmonics appeared to influence the electric power meter readings, and this specifically relates to reactive power. Incorrect power meter readings occur due to different so-called "measuring" protection levels in device circuitry in various devices. The paper analyzes reactive power meter readings of devices from various manufacturers. Based on the analysis, the authors introduce a new approach to evaluating the costs in connection to reactive power generation, transmission and consumption, with current/voltage distortions in power supply lines.
