Title: Innovative Contributions of James W Milligan in Electrical Engineering
Introduction
James W Milligan, based in West Lafayette, IN, is a notable inventor with a total of four patents to his name. His innovations primarily focus on enhancing the functionality and performance of watthour meters, which are essential in measuring electrical consumption for homes and businesses.
Latest Patents
One of his significant patents is the "Method and apparatus for adjusting overload compensation for a watthour," which details a mechanism for electrically setting the overload compensating magnetic reluctance in a single-phase induction watthour meter. The apparatus includes a moveable magnetic shunt that adjusts based on sensed electrical parameters, ensuring accurate readings even under variable conditions.
Another pivotal invention is the "Method for making a heat sensitive fault detecting and indicating device." This innovation is particularly designed for watthour meters and includes a layer of heatable material to indicate surges that may cause damage. When heat from a current surge melts a low melting point metal, this visually signals any potentially harmful incidents directly on the meter.
