The capacitor is detected using SVM and fused with the polar coordinate expansion method. The AOI system and the proposed fusion algorithm have been applied to the production line, with an accuracy of 99.73\% and a missed detection rate 0.12\%.
Similarly, the phasor diagram method is another traditional method used to detect faults in a capacitor bank. The results shown in Table 6 demonstrate that the phasor diagram method was highly efficient for detecting faults in capacitor bank and locating the fault phases and locations.
The unbalance in the voltage has to be detected and the unit must be isolated before significant damage occurs. There are many methods available for detecting unbalances in capacitor banks, but there is no practical method that will provide protection under all possible conditions.
In case of capacitor bank protection, it has illustrated that faults in a high voltage capacitor bank have been located by using the neutral current unbalance protection method [12, 13]. In the same way, phasor diagrams (arguments) have been used to locate faults in a capacitor bank.
Thus, the proposed algorithm effectiveness can be decreased in case applied to H-bridge connected of 230-kV level high voltage capacitor bank. An additional evaluation needs to be done before applied proposed algorithm on different voltage level and high voltage capacitor bank connection.
The case study shown in Table 6 demonstrates that while the EGAT was highly efficient at detecting faults, it could not indicate the fault position in the capacitor bank. The EGAT standard method identifies the fault phase and location manually. A worker must turn off the power to the system and waste time to find the fault position.
