When the variation of bus-barvoltage and frequency occurs, the reliability of electric motors, transformers, control and protection system is analyzed in this thesis.
In practical projects, while an asynchronous motor starting, the drop of voltage on the busbar must be within the limits which is stipulated by the national standard.
