| Abstract: | The principles for protection against earth fault fire and indirect electric shock in TN system and the necessity and practicality of adopting RCD which can automatically switching off fault circuit were discussed in the paper. At meanwhile, the introduction of how to reasonably select the action current of electric leakage, the protective functions of earth fault modulus of RCD-vigi that can meeting the re quirements above and the economy and practicality of adopting RCD were also explained by the actual examples of calculation. |
