In an overpotential test, excessive amounts of tracking were detected. Which point is recommended for first investigation?

In an overpotential test, the detection of excessive amounts of tracking indicates that there may be a breakdown of insulation or issues with the dielectric properties of the material being tested. When determining where to focus the investigation first, it is essential to consider areas known for vulnerabilities under stress.

Point 6 may be highlighted as a recommended starting point for investigation due to its likely positioning within a circuit or system where potential weaknesses, such as bends, connectors, or junctions, could lead to tracking. These areas often experience higher electrical stress, which can lead to insulation failure and resultant tracking.

Investigating this point first is strategic, as it targets a location where the conditions for tracking are most favorable, thus aiming to identify the root cause efficiently. By addressing the most probable source of the issue, further tests can be guided by initial findings at this point, making it critical in the troubleshooting process.
