摘要： In a utility monitoring system, a network of intelligent electronic devices (IEDs), including a master IED that receives master clock information from a global positioning system, includes a differential time synchronization (DTS) algorithm for automatically adjusting the corresponding clocks of each of the IEDs to be synchronized with the master clock information. A controller coupled to the network communicates instructions to the IEDs to collect frequency variation data. A known data alignment algorithm determines a point of alignment between two sets of frequency variation data, and the controller determines based on the data alignment algorithm output a time differential representing a time offset between the IED's clock and the master clock information. The time differential is communicated to the target IED, which advances or retards its clock based on the time differential.

摘要： A system and method for detecting and responding to device tampering in an EM device is disclosed. The EM device is provided with mechanisms to detect and indicate unauthorized tampering with the device. Further, in response to detected unauthorized tampering, the device may take actions to protect the integrity of data generated by the device as well as protect any confidential data stored within the device. Such actions may include preventing further device operation, generating warnings to the device owner/user, marking subsequently generated data as suspect, destroying stored confidential data, etc.

摘要： An intelligent electronic device (IED) includes a base module having a power monitoring circuit operative to monitor a parameter of a portion of a power distribution system and generate an analog signal representative thereof. The base module also includes a processor coupled with the power monitoring circuit, the processor having an analog to digital converter operative to convert the analog signal to a digital signal representative thereof. The processor operates to implement a first power management functionality and generate first power management data. At least one of a display and a communications interface couple with the processor and communicate the first power management data external to the IED. A first interface couples with the processor and the communications interface. The first interface operates to receive a first external function module. The first external function module includes a second power management functionality, where the first interface further facilitates implementation of the second power management functionality.
