摘要： The present disclosure provides for improving security in a meter or an intelligent electronic device (IED) through the use of a security key which is unique to each meter or IED. Such a key may be used to prevent password reuse among multiple meters. Such a key may also be used to encrypt critical components of the software, such that only when running on the correct meter can the components of the software be decrypted. Such a key may also be used to uniquely identify the device in a larger data collection and management system. The security key can also be used to prevent the direct copying of meters. The present disclosure also provides for a meter or IED that stores functional software separately from core software.

摘要： An intelligent electronic device IED has enhanced power quality and communications capabilities. The IED can perform energy analysis by waveform capture, detect transient on the front-end voltage input channels and provide revenue measurements. The IED splits and distributes the front-end input channels into separate circuits for scaling and processing by dedicated processors for specific applications by the IED. Front-end voltage input channels are split and distributed into separate circuits for transient detection, waveform capture analysis and revenue measurement, respectively. Front-end current channels are split and distributed into separate circuits for waveform capture analysis and revenue measurement, respectively.

摘要： An intelligent electronic device is provided including, inter alia, a processing unit configured to calculate energy consumed by at least one load and accumulate the calculated energy in a first volatile memory; the processing unit being configured to iteratively copy the accumulated energy from the first volatile memory to a first non-volatile memory after a first predetermined time period and copy the accumulated energy from the first volatile memory to a second non-violate memory after a second predetermined time period, wherein the first predetermined time period is longer than the second predetermined time period. The processing unit is further configured to copy the accumulated energy from the second non-violate memory to the first volatile memory upon startup or reset of the intelligent electronic device to avoid loss of data.

摘要： A system and a method is provided for the detection and capture, and in particular for an ultra high speed detection and capture, of transients in input voltages by an intelligent electronic device. The system and method detects transients for input voltages in either phase to phase or phase to neutral measurements and permits a user to set threshold levels for detecting transients in input voltages. In an embodiment, the system and method further provides a field programmable gate array as a controller for managing transient detection. The field programmable gate array includes a state machine for determining the state of the sampled signal with respect to a threshold level at a specified waveform sample period.
