Introduction to Partial Discharge Analysis
In High Voltage systems, insulations between conductors deteriorate over time due to wear and tear and weather conditions. Incipient faults may arise and lead to some electrical discharge/leakage in the system. If the problem goes unnoticed, it will pose an eminent danger of a flashover or electrical fire.
