Abstract

A sensor assembly includes an electrical conductor, at least one of a voltage sensor and a current sensor disposed about the electrical conductor, and a first insulator molded about the electrical conductor. The first insulator includes a plurality of structures structured to maintain concentricity between the electrical conductor and the at least one of the voltage sensor and the current sensor. A second insulator is molded about the first insulator and the at least one of the voltage sensor and the current sensor.

Description

technical field [0001] The disclosed concept relates generally to sensor assemblies and, more particularly, to sensor assemblies for electrical conductors, eg, current and / or voltage sensors for power supply conductors. The disclosed concepts also relate to methods of manufacturing sensor assemblies. The disclosed concept also relates to trip units that include sensor assemblies. Background technique [0002] Circuit interrupters, such as circuit breakers, protect electrical systems from electrical fault conditions such as current overloads, short circuits, or abnormal voltage conditions. Circuit breakers typically include a spring-powered operating mechanism that opens electrical contacts in response to abnormal conditions to interrupt electrical current flow through conductors of the electrical system. [0003] Vacuum circuit interrupters are commonly employed, for example, to reliably interrupt medium voltage alternating current (AC) as well as high voltage AC of severa...
