Abstract: Systems and methods for determining a voltage meter rating for a utility meter connected to a distribution system via one or more distribution lines. The system accesses voltage measurements provided by a meter that represent a voltage at different time intervals. The system filters the voltage measurements to remove any voltage measurements that fall outside a voltage range for the distribution line. The system further determines a measured voltage rating from a set of candidate voltage ratings for the meter. The system compares a stored voltage rating for the meter and the measured voltage rating to determine a confidence level for the measured voltage rating. When the confidence level for measured voltage rating exceeds a confidence threshold, the system uses the measured voltage rating to maintain the distribution system.

Abstract: Certain aspects and features include a system and method for monitoring the operational status of assets in an electric power distribution system. For example, an asset monitoring system identifies a zone of operation for an asset under evaluation. The asset monitoring application identifies meters connected to transformers in the zone of operation and obtains meter voltages for the meters over multiple intervals. The asset monitoring application determines a primary voltage for at least one transformer based on at least one meter voltage. The asset monitoring application uses the primary voltage in a power flow calculation to estimate an operational setting for the asset. The asset monitoring application compares the voltages from the power flow analysis using the estimated operational setting and the voltages from the meter voltages across multiple time intervals. Based on the comparison, the asset monitoring application determines an operational status of the asset.
