Abstract
A generator protection unit is provided including a central processing unit including at least one programmable device configured to utilize an Ethernet communication protocol. The central processing unit may be configured to synchronize a first signal generated by a generator electrically coupled to the generator protection unit to a second signal including an electrical power grid parameter of an electrical power grid, the first signal and the second signal having a phase offset. The generator protection unit may also include a plurality of multimeters, each electrically coupled to the electrical power grid and the central processing unit, and at least one display filter electrically coupled to the central processing unit and configured to separate a defined portion of a protection parameter signal, such that a remaining portion of the protection parameter signal is transmitted to the central processing unit. The generator protection unit may further include a user interface coupled to the central processing unit and configured to relay at least the remaining portion of the protection parameter signal to an operator of the generator protection unit.
