When the circuit breaker is open, a contact establishes an electrical connection between the transformer neutral and the substation ground. When the circuit breaker is closed, a spark gap limits the potential rise of the LV neutral with respect to the ground of the masses for a value greater than 10 kV. The circuit breaker is mounted inside a weather-resistant fiberglass-reinforced polyester box. Analog trip unit The operating principle is called \u201cthermal image\u201d. The thermal behavior of the transformer is reproduced in the unit by means of three thermistors thermally coupled together by a metal mass. Each thermistor, powered by a current transformer, carries a current proportional to the current flowing through each winding of the transformer. This allows for significant load imbalance between phases. The analog block is equipped with a charge indicator device.<\/p>","protected":false},"excerpt":{"rendered":"<p>Coffret disjoncteur Ces appareils (4 p\u00f4les dont 3 prot\u00e9g\u00e9s) sont \u00e0 coupure dans l\u2019air avec chambres \u00e0 cloisons m\u00e9talliques pour la coupure de l\u2019arc.
