Compact Voltage Sensor For Power-Lines

Power-lines for the distribution and transmission of high-voltage electricity are ubiquitous infrastructure of modern societies. Convenient means exists for measuring the currents in these power-lines. However measuring the voltages between conductors of power-lines is difficult and costly because it typically requires large and expensive equipment due to the high voltages (which can be tens or hundreds of thousands of volts). To address that situation, researchers at UC Berkeley have developed a novel, practical and inexpensive way to measure the conduct-to-conductor voltages of power-lines using components in just one conductor of overhead distribution and transmission power-lines. In addition to voltage, this technology can be augmented to measure current, power, and power flow directions. This Berkeley technology can also applied to power-lines in office buildings, factories and power substations.
