ABSTRACT:
An electrical power line transient noise filtering device is disclosed in the specification and drawings comprising a step up transformer connected to two continuous resistors. The high voltage winding of a step down transformer is connected to the other ends of the resistors. Low frequency power passes easily through the system but noise pulses are effectively blocked because they must pass through a transmission line of high loss.
