    Abstract: A distribution transformer having a coil assembly mounted to a ferromagnetic core. The coil assembly includes a resin-encapsulated low voltage coil mounted to the core, a resin-encapsulated first high voltage coil disposed around the low voltage coil, and a resin encapsulated second high voltage coil disposed around the first high voltage coil. The first high voltage coil is separated from the low voltage coil by an annular first space, and the second high voltage coil is separated from the first high voltage coil by an annular second space. The low voltage coil and the first and second high voltage coils are arranged concentrically. The low voltage coil and the first and second high voltage coils have different axial lengths.

    Abstract: The present invention is directed to a method of making a transformer having a stacked core, which includes top and bottom yokes and first and second outer legs. The core also includes an inner leg that is formed from a pair of stacked plates, which abut each along a seam that extends in the longitudinal direction of the inner leg. Each of the upper and lower yokes may be formed from a single stack of plates, or a plurality of stacks of plates. Each of the inner and outer legs may also be formed from a single stack of plates, or a plurality of stacks of plates. The cross-section of the core may be rectangular or cruciform.

    Abstract: Un conmutador con conexión a tierra está constituido de un bastidor estructural, por lo menos un primer contacto, por lo menos un segundo contacto, por lo menos un separador y un montaje impulsor engranado. La apertura y cierre del conmutador con conexión a tierra se controla por el montaje de impulsor engranado. El montaje de impulsor engranado es operable para hacer girar por lo menos un segundo contacto alrededor del eje de una varilla de conexión para mover por lo menos un segundo contacto dentro y fuera del contacto con por lo menos un primer contacto. El cierre del conmutador con conexión a tierra del primero y segundo contactos sirve para conectar un transformador u otro dispositivo eléctrico a potencial con conexión a tierra.
