Abstract

See full text

An Intelligent Electronic Device (IED) for measuring a zero-crossing based electrical parameter when there is power quality disturbance in the power supply network. More specifically, the IED includes at least one sensor configured for sensing at least one electrical parameter of electrical power distributed from an electrical distribution system to a load, at least one analog-to-digital converter coupled to the at least one sensor and configured for converting an analog signal output from the at least one sensor to digital data, at least one processing module coupled to the at least one analog-to-digital converter, the at least one processing module is configured to receive the digital data, determine that the IED enters loss of synchronization according to the received digital data, measure a zero-crossing based electrical parameter of the digital data according to the cycle of the digital signal immediately before loss of synchronization.
