Abstract
A synchronized pseudorandom sequence injector is provided for injecting a plurality of pseudorandom signals at selected locations in a power system having a plurality of locations forming a transmission and distribution grid. A synchronization pulse generator generates an accurate reference clocking signal. A pseudorandom clocking and sequence generator receives the clocking signal and generates a string of pseudorandom sequences. A binary drive control creates a tri-state voltage output from a logic level output of the pseudorandom clocking and sequence generator. A signal conditioning interface processes the voltage output to attenuate any protection related carrier signals from a pseudorandom signal injection point at a selected location.
