Abstract
Systems and methods that measure electrical parameters of a multi-phase electrical system may utilize a multi-phase measurement device that includes a sensor subsystem that has a voltage sensor and a current sensor. Each of the voltage sensor and the current sensor may be a contact-type sensor or a “non-contact” sensor that does not require galvanic contact. In operation, a multi-phase measurement device may utilize the voltage sensor and the current sensor to sequentially obtain single phase measurements for each phase of a multi-phase electrical system. The measurements may be synchronized to obtain various multi-phase power parameters, such as various parameters relating to power, phase, voltage, current, etc. The multi-phase measurement device may be operative to automatically detect when an operator has positioned a sensor of the sensor subsystem proximate a conductor under test so the multi-phase measurement device can initiate detection of one or more electrical parameters in the conductor.
