A network device operable to receive and forward communications over a network through at least a first network connection and a second network connection. The network device includes a bypass module having a first device network connection and a second device network connection. A controller is operative to receive control signals originating external to the network device, and to selectively switch switching elements of the bypass module between a bypass state and a connected state based on the received control signals. The first network connection and the second network connection in communication with the first device network connection and the second device network connection in the connected state. The first network connection and the second network connection in communication with each other establishing a bypass communication path in the bypass state.

Network device mounting rail for connecting removable modules

An intelligent electronic device (IED) configured to supervise a process having a state has at least one of a current, voltage or resistive input configured to monitor the state of the process, a binary status input configured to monitor the state of the process, a binary status input configured to receive a digitally encoded serial communication package for monitoring the state of the process, a control output configured to output a signal to control process protection, control, or automation, or a combination thereof, or a control output configured to output a digitally encoded serial communication package to control protection, control, or automation, or a combination thereof. The IED is also configured to facilitate digital communication between at least two compatible devices by directing communication packets from ports connected to an originating compatible device to ports connected to a destination compatible device.

Intelligent electronic device with embedded multi-port data packet controller

A system for protection, control, metering, and monitoring of the delivery of electrical power is disclosed. Embodiments of the system provide input/output devices called bricks to receive analog and binary field data from primary equipment located in a power substation switchyard. The bricks are linked via fiber-optic patch cables and patch panels with one or more intelligent electronic devices ('IEDs'). In operation, the bricks convert the received binary and/or analog field data into digital signals, and transmit the digital signals synchronously to their associated IEDs using clock signals provided by each IED to the individual bricks. The bricks may accept a computer software code download from each of its master IED(s). Multiple code implementations, each tailored to the requirements of its master IED(s) can therefore co-exist on a single brick.

Protection and control system for electric power networks with signal and command interfaces at the primary equipment

There is provided a method of testing an electrical switchgear system. A node in the electrical switchgear system monitors a power line signal and controls a breaker based on the power line signal. The method includes applying an analog signal to the node, and receiving data representing a status of the breaker. The analog signal simulates the power line signal.
