| Resumen |
Description of a new system for protection against direct contact with conductors carrying voltages of 3 to 10kV: when a person is in contact with one phase, the amplitude of this phase is disturbed, which enables it to be detected and earthed, while the current is cut on the line where the contact occurred. The contact duration is limited to 10ms at most, and the current through the body does not exceed 10mA. |
