N2 - – Ferroresonance is a phenomenon that occurs in the transformer core, and is characterized by the presence of abnormal voltages. An electrical circuit that can cause ferroresonance has elements of resistance (R), capacitance (C), and non-linear inductance (L). In this research, the phenomenon of a surge in the value of the transformer current and voltage, which has changed drastically (jump phenomenon) after being triggered by an increase in the source voltage of about 1%, has been found out. The emergence of this jump phenomenon can trigger the emergence of ferroresonance. This will cause the transformer not to work normally in its linear region but in non-linear (saturation) regions. The test has been carried out on a 220 V 3-phase low-voltage transformer with H-core type and M-core type. Then the initiation factors such as source voltage variation and capacitance variation have been given to the system. Trends in the waveforms of voltage, current, voltage at source, transformer capacitor have been analyzed. The test results have showed that the given initiation factor can explain the correlation between the jump phenomenon characteristics and the presence of ferroresonance in the H-core and M-core transformers. When ferroresonance has appeared, the voltage value has been relatively high in the H-core type transformer. The largest value of voltage and current of the transformer occurs at 30 uF in S-phase with a transformer voltage value of 265.8 V and a current value of 5.7 A. Whereas, the ferroresonance mode in H-core and M-core is the fundamental ferroresonance mode.
