VIBRATING POINT REGULATOR
FIGURE 15. VIBRATING POINT REGULATING CIRCUIT.
Description
The vibrating point voltage regulator is a single-element unit that limits system voltage. The
element consists of a double set of contact points that are operated by a magnetic coil. The center
contact is stationary and connected directly to the generator field. The upper and lower contact
points are pulled downward by the magnetic coil against the force of a spring. The upper and
lower contacts always maintain the same distance from each other. The upper contact is shunted
directly to the ground.
