Applicable Scenarios:
1. High-resistance breakdown points in cables after installation, especially linear high-resistance breakdown points that are difficult to burn into low-resistance states, such as linear high-resistance breakdowns at cable joints.
2. Flashover-type breakdown points, where a constant current source can maintain the arc after breakdown, a stable current flows through the bridge circuit, and the bridge has sufficient sensitivity.
3. Defects that have not yet broken down but have low resistance, such as insulation defects where a megohmmeter reveals a low cable resistance, but the cable does not break down under operating voltage.
