Abstract
Human safety against touch voltage hazards is the most important factor in electric power systems. Danger of touch voltage can occur if humans touch the live parts directly or indirectly. Indirect touch can occur when humans touch the open conductive parts (BKT) of equipment which under normal circumstances has no voltage but can be live due to leakage current due to damage to insulation in electrical cables. Therefore it is necessary to protect against indirect touch voltage. This study aims to analyze indirect touch voltage protection using Earth Leakage Circuit Breaker (ELCB) and Miniature Circuit Breaker (MCB). In this study, 30 mA ELCB and 2 A MCB were used as protection against indirect touch voltage hazards. The research data were obtained by using the experimental method, namely by conducting experiments in the laboratory. From the experimental results in the laboratory, it was found that the 30 mA ELCB is more sensitive as protection against indirect touch voltage than the MCB. This is because the working principle of the ELCB is based on the leakage current that occurs in the BKT, while the working principle of the MCB is based on the total current (leakage current and load current) flowing through the MCB.
