Abstract
Systems and methods to determine open neutral conditions in a poly-phase electrical connection. Voltage measurements of at least two phases of poly-phase electrical power delivered to a customer premises are received from an electrical meter via a communications network providing communications among many electrical meters. The electrical power is delivered with a neutral conductor separate from the at least two phases. A first voltage measurement of a first phase and a second voltage measurement of a second phase of at least two phases are received. Based on determining that a difference between the first voltage measurement and the second voltage measurement exceeds a phase-to-phase threshold amount, a likely open neutral condition in the neutral conductor is determined. An indication of the likely open neutral condition is sent to a customer service system.
