Hot stick power analyzer

摘要

A hot stick power analyzer includes a housing mounted on a pole and a channel for a power line. A ground line extends from the housing and there is a power line conductive contact. A voltage sensor includes voltage sensing circuitry connected to the power line conductive contact and the ground line. There is a high voltage capacitance between the ground line and the voltage sensing circuitry. A current sensor includes windings about and spaced from the power line. A processing subsystem is responsive to the voltage sensing circuitry and to the current sensor and is configured to compute power analysis metrics.
