FAQ

 

Q: Why is partial discharge testing important?

A: Partial discharge testing is essential for early detection of insulation issues in high-voltage electrical equipment. It prevents catastrophic failures, assesses insulation health, optimizes maintenance, enhances safety, and ensures compliance with industry standards. This testing is crucial for maintaining reliability and preventing unexpected breakdowns, ultimately extending the lifespan of electrical assets.

 

Q: What are the different types of partial discharge?

A: Partial discharges occur in various forms, including corona discharge, surface discharge, internal discharge, corona pulse discharge, and localized partial discharge. They result from ionization of air, imperfections on surfaces, or within insulation materials, depending on specific conditions and structures of electrical components.

 

Q: How do you measure partial discharge in cables?

A: To measure partial discharge in cables, specialized equipment like a partial discharge (PD) detector is used. The process involves applying high-voltage stress to the cable and monitoring the electrical signals produced during partial discharge events. The PD detector captures and analyzes these signals, helping to identify and assess the severity of partial discharges in the cable’s insulation.

 

Q: What is a partial discharge test in high voltage?

A: Cable partial discharge testing, done online or offline for medium to high voltage power cables, detects small insulation defects causing discharges across sections of the insulation. Online testing provides real-time insights during operation, while offline testing, conducted when cables are out of service, offers a comprehensive examination.
