Abstract
Voltage sag has become one of sharpest issues on power quality in modern social. In this paper, voltage sags indices such as SARFI, severity index, energy index are summarize, analyzed and compared, and the energy index is improved. Four indices are proposed, that is: statistical index, severity index, event time indices and cost indices, and the recommended reason is also explained.
