An intelligent electronic device (IED) is connected to interact with a power system to provide protection, control, and/or monitoring capabilities for the power system. The device includes a power system interface circuit for communicating with the power system and a processor coupled to the power system interface circuit. The device further includes memory storing software instructions performed by the processor for receiving electronic mail from a remote system through a communication link and for automatically transmitting electronic mail to the remote system through the communication link. The electronic mail may include information relating to operation of the power system or to operation of the intelligent electronic device.

Electronic communications in intelligent electronic devices

A system for controlling and monitoring operation of an electrical system is described. The system includes a fault protection device, for example, a circuit breaker, that is connected to the electrical system to provide fault isolation. The system also includes a protection system that includes an interface and a logic system connected to the electrical system. The logic system is connected to the interface and controlled by a processor to receive input from the electrical system and input from a user through the interface. The logic system operates the fault protection device when the received input from the electrical system indicates a fault event. Additionally, the logic system indicates information relating to operation of the electrical system through the interface. The system further includes one or more dedicated switches connected to the fault protection device and to the interface to directly present to the operator the breaker status indications and to directly operate the fault protection device in response to input received from the user through the interface in the event that the logic system experiences a failure.
