Ensuring that service voltage is within ANSI limits is a basic but important step in delivering power. Sophisticated programs such as Conservation Voltage Reduction (CVR) and volt/VAR optimization require continuous steady-state monitoring as switch operations are made by the system. These steady-state voltage measurements should include the effects of voltage sags and other short-term excursions. On the other hand, a fast response and near real-time readings are needed for immediate feedback for automatic systems......Download to continue reading!
