摘要： A power meter or other electrical device is provided having two independent and communicatively isolated Ethernet ports. The first Ethernet port is addressable by a first unique identifier and is configured for enabling full access to the power meter via an internal LAN. This enables a LAN operator to remotely access the power meter via the internal LAN for performing metering functions, such as full telemetry, control and programming. The second Ethernet port is addressable by a second unique identifier and is configured for being connected to the Internet. Since the second Ethernet port is communicatively isolated from the first Ethernet port, a user can access the power meter via the Internet, but cannot access the internal LAN by connecting to the power meter via the Internet.

摘要： Devices, systems and methods for authenticating a user of an intelligent electronic device (IED) using dual factor authentication is provided. The present disclosure provides for receiving user credentials at an IED, determining a user and a preferred mode of communication based on the user credentials, sending a code to the user via the preferred mode of communication and receiving the code entered at the IED. Upon matching the generated code to the received code, access is granted to features of the IED. Additionally, the present disclosure provides for receiving user credentials at a remote server, determining a user and a preferred mode of communication based on the user credentials, sending a code to the user via the preferred mode of communication, receiving the code entered at the remote server, and providing remote access via a network to an IED by authenticating a user remotely.

摘要： An intelligent electronic device (IED) includes an image capture module configured for capturing images or video in a location of the IED. The IED may also include a heat sensor for sensing heat inside or outside a housing of the IED. In one application, these techniques are implemented in IEDs such as electrical power and energy meters and used to control access to reset, configuration, billing, communication, and data acquisition/processing functions of the meters. Additionally, image processing techniques are employed by the IED to detect events in an electrical distribution system and implement control functions thereof.

摘要： Apparatuses, systems, and methods for providing security in an intelligent electronic device (IED) are provided. In one aspect of the present disclosure, an IED is provided including at least one processor that receives a communication via a communication interface, the communication including an unencrypted file and a digital signature. The at least one processor decrypts the digital signature to obtain a first value, executes a hash function on the unencrypted file to obtain a second value, determines if the first value and second value match, and updates at least one firmware package stored in at least one memory of the IED with the unencrypted file if it is determined that the first value and the second value match.

摘要： An intelligent electronic device (IED) includes a user authentication module configured for authenticating authorized users of the IED and preventing an access by non-authorized personnel to a user-selectable portion of operational features of the IED. In exemplary embodiments, the user authentication module includes a database of information authenticating an authorized user and a sensor acquiring user-identifying information (e.g., a biometric sensor, a reader of magnetic, holographic, RFID, or smart ID cards, or a keypad). In one application, these techniques are implemented in IEDs such as electrical power and energy meters and used to control access to reset, configuration, billing, communication, and data acquisition/processing functions of the meters.

摘要： A device and method are provided for managing flash memory of an intelligent electronic device (IED) to maximize the IED life. The IED includes at least one sensor for sensing at least one electrical parameter distributed to a load. At least one analog-to-digital converter is coupled to the at least one sensor for converting an analog signal output from the at least one sensor to digital data.
