Diferenças entre 220v trifásico e monofásico
O tipo de fornecimento de energia é definido de acordo com a necessidade da residência ou empresa e conforme a carga de energia necessária para que todos os equipamentos funcionem corretamente. Esses são os tipos de fornecimento de energia:
Monofásica
A rede monofásica é feita com dois fios, um fase e outro neutro. Na rede urbana, resulta na tensão de 127V e é capaz de alimentar 8000 watts de potência. A tensão monofásica muitas vezes é chamada de 110v no vocabulário do leigo. Embora não seja um erro grave, o correto é falar a tensão de 127 V.
Bifásica
A ligação da rede bifásica é feita com três fios, dois fases e um neutro. Resulta na tensão de 220V bifásico e consegue atender entre 12.000 e 25.000 Watts de potência. Coloquialmente, essa ligação pode ser chamada de “220v monofásico” para se diferenciar do 220v trifásico mas é importante salientar que, tecnicamente, o 220v monofásico surge da ligação da fase e neutro nas redes industriais de 380v. Esse tipo de distribuição é normalmente instalada em regiões rurais, pois não haverá tanto consumo de energia como nas áreas urbanas ou, a depender do estado, também nas cidades.
Trifásica
A instalação da rede trifásica é feita com quatro fios, três fases e um neutro. As voltagens são 220V ou 380V e alcança a potência de até 75000 watts.
Corrente Contínua e corrente alternada
A principal diferença entre corrente alternada e contínua reside no fato de que a corrente contínua (CC) não altera o seu sentido de circulação dentro do circuito elétrico. Por outro lado, temos que a corrente alternada (CA) consegue alterar seu sentido. Essa é a diferença básica entre elas.
Diferença de tensão entre fases e tensão entre fase e neutro
A Diferença de tensão entre duas fases resulta no valor de tensão 220v bifásico e a diferença de tensão entre fase e neutro resulta no 127v monofásico.
