Title: Albert S. Crane, Jr.: Innovator in Current Measurement Technology
Introduction
Albert S. Crane, Jr. is a notable inventor based in Portland, OR (US). He has made significant contributions to the field of current measurement technology, holding a total of 3 patents. His work has been instrumental in advancing the capabilities of current sensing circuits and temperature monitoring methods for transformers.
Latest Patents
One of his latest patents is a "Current Sensing Circuit for Use in a Current Measurement Probe." This invention features a transformer that allows a current to be measured by inducing magnetic flux into a magnetic core. The core includes a magneto-electric converter that senses DC to low-frequency current signals, along with a secondary winding for higher frequency signals. The output from the magneto-electric converter is amplified and processed through a transimpedance amplifier, which serves dual functions as a power amplifier and a transimpedance gain amplifier.
Another significant patent is the "Method of Monitoring Current Probe Transformer Temperature." This method determines the initial temperature of the current probe transformer based on the winding resistance. It also assesses the temperature of the Hall Effect device through resistance changes. By combining these temperature readings, a continuous temperature indication of the transformer is produced. If the temperature exceeds a certain threshold, the current signal is removed, and a visual alert may be provided.
