Abstract

Currently, many industries use DC power as a power supply for controller equipment, etc. All companies want their DC system to be reliable. One effort to maintain the reliability of the DC system is to monitor the leakage current in each branch of the DC system load. Leakage currents that occur if not discovered early on will gradually result in short circuit currents and instability of the DC system. This research wants to use the hall effect to detect leakage currents in branch loads using the difference in current in the positive (+) and negative (-) cables. Use the right-hand law for the direction of the magnetic field. Insert the positive (+) and negative (-) cables into the same Hall sensor where the resultant magnetic field will be 0 under normal circumstances and >0 or <0 if there is a leakage current in one of the cables. Because of this, the Hall effect can be used to detect leakage currents (Ground Fault) in DC systems. Another advantage of the Hall effect is that it monitors DC system leakage currents continuously while operating.

Abstract

Protection relay devices are very important in the electrical system where they act as voltage breakers when there is a disturbance in the electrical system so that electrical equipment and those connected to it are not damaged. Based on the IEC 60255 standard, protection relay devices are required to be reliable, fast, and selective so that the electrical system is protected from disturbances and works properly without miss-operation. The standard tolerance for the verification value deviation is not more than 5% of the setting value, this refers to the IEC 60255 standard. This journal explains the testing of setting valuesand time delays on protection relay devices that focus on differential current protection. The results of this test can be concluded whether the protection relay is still suitable for use or not with a standard tolerance deviation of ≤5%.
