The goal of passive components’ failure analysis (FA) is to determine the root cause for an electrical failure. The findings can be used by the manufacturers to improve upon the design, materials, and processes used to create their components. This leads to better quality and higher reliability components. The FA also.

A method based on argument analysis of the current phase and unbalanced current was developed to identify the fault location in a capacitor bank. As shown in Fig. 3, the proposed method is organized into two procedures: (1) checking the fault phase in the capacitor bank and (2) identifying the fault location in the capacitor bank.

Although the PMBOK Guide outlines a methodology for managing risk, its process for identifying risk--this author observes--lacks internal structure. Because of this lack, project managers may find it difficult to decide which tool to use, as well as understand why and how to use it. This paper examines a logical approach for applying the PMBOK Guide''s

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 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.
Therefore, failure analysis of integrated capacitors is the key to identify the root cause but, on some cases, is also a challenging task. Three case studies were discussed that includes the FA approaches and techniques that were utilized to understand the defect sites.

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.
Advancements in failure analysis have been made in root cause determination and stress testing methods of capacitors with extremely small (approximately 200 nm) defects. Subtrac-tive imaging has enabled a non-destructive means of locating a capacitor short site, reducing the FIB resources needed to analyze a defect.
