One problem that is pervasive in the power grid and not well understood is called the Transient Recovery Voltage (TRV). When a short-circuit due to a fault in high voltage or medium voltage system is switched-out by a circuit breaker, …
With the advent of modern microprocessor relaying, much of the communication between relays has been shifting from power-line-carrier apparatus or microwave to fiber. Since power utilities own the easements for the high voltage transmission lines, it is only logical to install …
Have you wondered what goes on behind the scenes of electric power delivery in America? This post explains who is controlling the flow of power on the grid and who is policing to ensure the reliability requirements are met.
In this post, we calculate the full load current drawn by the load. See linked post to view how the per unit impedances were calculated.
