The Study on The Effectiveness and The Importance of Spark Test to The Earthing in The Single-Phase Housing System

Abstract

The spark test is the alternative way of earthing safety testing that usually being measure by an earth electrode tester. The more professional way is by using CDEGS. This system testing has been developed specifically and suitable for housing systems and not for industrial. A simple housing system has been made for this project that has a socket outlet connection. The housing system consists of a 230 V socket supply, Main Switch, RCCB with 0.1 A sensitivity, and MCB 20 A that connects with the socket outlet. The spark testing has been made by two conditions which is the housing system that has the connection of earthing being spark of neutral cable to earthing terminal and one more is sparking the neutral cable to earth terminal that does not have an earthing connection. The measurement of voltage and current also has been made using the multimeter and clamp meter to measure the leakage voltage and current in on-off condition without load before and after the spark test. The measurement of total voltage and current has also been taken for a full load. The finding of this project has shown that earthing connection systems are important in residential. The leakage voltage and current still able to measure in this smaller scall housing system. Leakage voltage was not able to be earthed and the residential system (RCCB) cannot detect it if the earthing connection does not correct or has a problem. The power supply will not be cut off and the leakage still flows in the residential that can cause harm and bad incident not only to human, but also no other living things
