You might wonder why it’s crucial to perform HiPot testing on a 25 MVA power transformer. In this instance, the transformer was hit by a lightning strike and has been producing gas since. Our client sought to determine if there was an imminent risk to the equipment.
To address this, Megavar’s technicians deployed our 300kV resonant HiPot unit for the task. We’re pleased to report that the transformer has passed the test and remains in service!
What is HiPot Testing?
“HiPot” (short for High Potential) testing, also known as high voltage testing or dielectric withstand testing, is a method used to verify the electrical insulation integrity of a device or component. For transformers, HiPot testing ensures that the insulation system can withstand high voltages without breaking down.
Why is HiPot Testing Important?
- Safety Assurance: Verifies that the transformer can safely operate at high voltages, preventing electrical shock or fire hazards.
- Risk Mitigation: Identifies potential insulation breakdowns or weaknesses that could lead to equipment failure or safety issues.
- Operational Reliability: Ensures the transformer remains reliable and efficient, minimizing the risk of unexpected outages or failures.
At Megavar, our commitment to thorough testing and safety helps ensure that your critical infrastructure operates smoothly and reliably.
