Abstract :
Description of newly designed watthour meter light load and inductive load adjustments having only one moving part in each. A conductive plate, here-tofore movable, now with three circuits, is fixed in position. The two outer circuits, oppositely displaced from center, are loaded by coils through which moves a magnetic screw for adjusting light load. The phasing adjustment is a similar screw, moving in a coil that loads the center circuit, simultaneously changing the gap in a magnetic circuit which picks up leakage flux for torque compensation and is located to avoid differential shunting of the side arm gaps.
