This paper presents an Active Correlation Technology (ACT) for voltage sag detection and control. ACT is a conceptual architecture developed by IBM and can be successfully implemented to manage maintenance activities of distribution networks. As an instrument, maintenance clearly impacts on system reliability and quality of supply, i.e., very limited maintenance will result in an excessive number of costly failures and poor system performance, and therefore, reliability and quality of supply are degraded; done often, both reliability and quality of supply may improve but the cost of maintenance will sharply increase. Efficient maintenance schemes consider condition monitoring and maintenance activities are performed when a threshold pattern is violated. In this paper, a correlation engine is proposed to set voltage sag threshold patterns to detect abnormal sag incidence on MV feeders and trigger alarms to indicate the need for maintenance activities. The central ideas are validated with records obtained from a medium voltage circuit operated by one of the distribution divisions of the Mexican utility.
