Proteksi pada Instalasi Listrik dengan Elcb Elektronik

Abstract

Security factor on electricity installation is the main consideration, because of function to prevent the damage on electronic devices caused by short-circuit and leakage current. In general this circumstance used MCB (Miniature Circuit Breaker) and ELCB (Earth Leakage Circuit Breaker) which assembled in house installation system. This research aims to created installation protection system with ELCB 3 Ampere. This system used current sensor to read the current that is passed by phase and neutral, TRIAC serve as switch to cut off and connect the current from load. Microcontroller serve as trigger gate from TRIAC based on input data from current and voltage sensor. Of the test result if current flowed over 3 Ampere, TRIAC switch will cut off.
