Abstract
An intelligent electronic device (IED) for monitoring at least one power parameter in a power system is disclosed. The IED comprises at least one voltage input operative to be coupled with at least one power line in the power system and operative to sense at least one voltage in the power system. The IED further comprises at least one current input operative to be coupled with the at least one power line and operative to sense a current flowing through the at least one power line. The IED further comprises at least one analog to digital converter coupled to the voltage input and the current input and operative to produce digital samples indicative of the voltage and current. The IED further comprises a processor coupled with the at least one analog to digital converter and operative to calculate the at least one power parameter. The IED further comprises a power supply operative to supply power to the IED. The IED further comprises a transceiver operative to communicate at least one data packet comprising the at least one power parameter via time domain pulses of RF energy occupying a wide range of frequencies and an antenna coupled with the transceiver operative to transmit the RF data packet.
