High voltage testing

High voltage testing is a process used to verify the insulation strength of electrical equipment, like transformers or cables, by applying a voltage much higher than normal operating levels. This test ensures the equipment can withstand electrical stress without breaking down or causing faults. It identifies potential weaknesses or defects in insulation materials, preventing future failures. The test is conducted in controlled conditions by trained professionals, using specialized equipment to safely generate and measure the high voltage. Ultimately, it helps confirm the reliability, safety, and durability of electrical systems before they are put into service.
