Title: Michael J Estes: Innovator in Electrical Engineering

Introduction

Michael J Estes is a notable inventor based in Waukesha, Wisconsin. He has made significant contributions to the field of electrical engineering, particularly in the development of advanced relay systems and temperature sensing devices. With a total of two patents to his name, Estes has demonstrated a commitment to innovation and practical solutions in high voltage power applications.

Latest Patents

Estes' latest patents include the "Multiple Range Inverse Time Overcurrent Relay" and the "Temperature Sensing Transformer Primary Switch." The Multiple Range Inverse Time Overcurrent Relay is designed to trip a circuit breaker in high voltage power lines. This relay features a current transformer with first and second turns ratios, a heat radiation circuit with multiple lamps, and a sensing circuit that utilizes a phototransistor to respond to heat radiation. The design allows for different minimum trip current levels by selectively connecting the turns ratios and lamps.

The Temperature Sensing Transformer Primary Switch is another innovative creation by Estes. This switch is mounted within a distribution transformer below the level of the dielectric fluid. It is manually operable from outside the transformer, allowing for the opening of the primary circuit and de-energizing the transformer. The switch includes a temperature sensing device that opens the primary switch in response to overload temperatures on the transformer's secondary circuit. This device incorporates a compression spring and a wax motor, which work together to release energy stored in the spring when the dielectric fluid reaches a predetermined maximum temperature.
