Title: Dorr Kimball: Innovator in DC Ground Fault Detection

Introduction

Dorr Kimball is an accomplished inventor based in Alhambra, California. He holds three patents, showcasing his expertise in the field of electrical engineering, particularly in ground fault detection systems.

Latest Patents

One of Kimball's latest patents is an apparatus for the detection of ground leakage in a normally ungrounded DC system. This innovative device includes a DC power supply and conductors that supply power to a load connected to the DC system. An indicator is connected between the DC system and a ground point, allowing for the detection of ground leakage. When a ground leakage occurs, it closes a circuit to activate the indicator. A pulser periodically interrupts the circuit, generating an interrupted ground fault signal. This signal is detected by a sensor positioned relative to the DC system, enabling the location of the ground fault. The sensor also suppresses noise introduced into the pulse signal during the ground fault occurrence.

Career Highlights

Throughout his career, Dorr Kimball has worked with notable companies, including Southern California Edison. His contributions to the field have been significant, particularly in enhancing safety measures in electrical systems.

Collaborations

Kimball has collaborated with professionals such as Michael G. Cox and Manuel R. Cabison, further enriching his experience and expertise in the industry.

Conclusion

Dorr Kimball's innovative work in DC ground fault detection has made a substantial impact on electrical safety. His patents reflect a commitment to advancing technology in this critical area.
