Overall Conclusions � The most severely effected is the computer as sag can cause loss ong>ofong> data � No damage occurred on any ong>ofong> the loads � The sag may stop the air conditioners in the residential areas due to sags � The restart can produce over load if all airconditioners are started simultaneously and further sags can occur. � In residential areas, the sag has minimal financial consequences to the owners 66

Contribution ong>ofong> the Project � Has provided the utilities and the customers with the information that voltage sags are not a serious cause ong>ofong> concern in residential areas � Has provided the utilities and the manufacturers ong>ofong> sensitive equipment with CBEMA curves which will inform them about the sensitivity ong>ofong> the equipment � Has provided the utilities with a prediction table ong>ofong> a single apartment which will help in predicting the performance ong>ofong> loads on being subjected to voltage sags 67
