Sensor of the control so as to be taken to mean current voltage laterally of a tip of access and its application to the testing of a network

摘要

A medium voltage socket has a lateral access orifice (18) which allows the attachment of a control sensor box (27). The control sensor box (27) houses a voltage sensor and a current sensor with receiving circuits (28,29) connected (30) to an external source of supply. The voltage sensor consists of a voltage divider whose upper electrode is connected by a coiled spring (51) to the receiving electronic card (29) and includes an indicating light (54). The current sensor is a Hall effect element connected to an electronic card (28) which subtracts the continuous component.
