Você sabe por que o neutro é aterrado no padrão de energia? Esse aterramento é chamado de aterramento funcional e tem a função de referenciar o neutro ao potencial da terra, ajudando a manter as tensões do sistema estáveis. É por isso que a tensão entre fase e neutro que chega à residência tende a permanecer próxima dos valores esperados, como 127 V ou 220 V, dependendo da tensão fornecida na região. #eletrica #engenharia #eletricista #eletricidade #eletricaresidencial
