Abstract: In accordance with the disclosed subject matter herein, an apparatus for suppressing in a split-phase power system, effects of line-to-ground transient voltage spikes, balancing phase voltage with respect to ground, filtering phase voltage harmonics, cleaning up electrical noise in a split-phase power system, redirecting energy and absorbing electrical noise, protecting or replacing typical TVSS (transient voltage surge suppressor) units. The apparatus of the present invention can not be damaged by electrical noise. It uses virtually no energy in monitor mode and cannot draw over 3 amps. The apparatus of the present invention can be applied to single-phase lines from center tapped delta power transformers. In some embodiments of the disclosed subject matter, an apparatus for use with a power supply bus having at least a first power line and a second power line.
