Title:
MULTI-SENSOR SCANNER CONFIGURATION FOR NON-CONTACT VOLTAGE MEASUREMENT DEVICE
Document Type and Number:
Japanese Patent JP2023052672
Kind Code:
A
Abstract:
To provide a system and method for measuring the AC voltage of an insulated conductor without requiring a galvanic connection between the conductor and a test electrode.SOLUTION: A non-galvanic contact voltage measurement system includes a sensor subsystem, an internal ground guard, and a reference shield. A common mode reference voltage source 130 is electrically coupled between the internal ground guard 132 and the reference shield 134 to generate AC reference voltage which causes a reference current to pass through a conductive sensor 126. A control circuit receives a signal indicating a current flowing through the sensor subsystem due to the AC reference voltage and AC voltage in an insulated conductor, and determines the AC voltage in the insulated conductor on the basis at least in part of the received signal. The sensor subsystem includes a plurality of sensors that are polled to compensate for a conductor position while allowing measurement of the physical characteristics of the conductor.SELECTED DRAWING: Figure 2
