Fault Diagnosis Guide

Understanding Breakdown Phenomena

During cable DC testing, two fault types may occur:

Flashover faults indicate weak insulation points without permanent channels - evidenced by temporary breakdowns that self-recover when voltage is removed.

Operational Modes

• Manual Ramp: User-controlled voltage increase

• Auto Sequence: Programmed multi-point testing

• Leakage Scan: Current measurement at preset levels

Configured for your specific test requirements - choose optional infrared ammeter or integrated 40kV units for field testing.
