System and Method for Monitoring a Power Line without Connecting to Ground

摘要

An improved system and method for monitoring power tines without connecting to ground is disclosed herein. An improved sensory assembly can comprise a first end, a second end, a voltage sensor, a current sensor, an analog to digital converter, and a sensory transceiver. The first end can be electrically connectable to a first phase of a power line. The second end can be electrically connectable to a second phase of the power line. The voltage sensor can be capable of measuring a voltage between the first phase and the second phase. The current sensor can be magnetically coupled to the power line. The analog to digital converter that can be capable of receiving a first signal from the voltage sensor, and can be capable of receiving a second signal from the current sensor.
