At KC India Test Laboratories LLP, we specialize in providing precise and reliable Partial Discharge (PD) Testing for a wide range of electrical equipment. Partial discharge is a localized dielectric breakdown in an electrical insulation system under high voltage stress, which does not completely bridge the space between two conductors. While it may appear minor initially, if left undetected, partial discharges can deteriorate insulation, leading to equipment failure, fire hazards, and costly downtime.
What is Partial Discharge Testing?
Partial discharge testing is a critical diagnostic method used to detect, locate, and evaluate weak spots or faults in the insulation of medium and high-voltage equipment. It is especially important in evaluating:
- Power transformers
- Switchgear
- Rotating machines (motors and generators)
- Cables and accessories
- Bus ducts
- Insulators and bushings
These discharges are symptoms of defects such as voids, cracks, or contaminations within the insulation, and over time, they can evolve into complete breakdowns.
Importance of PD Testing
- Prevention of Failures: Early detection of partial discharge allows maintenance teams to address insulation degradation before it results in costly damage or failure.
- Quality Assurance: For manufacturers, PD testing ensures that products meet design and quality specifications before dispatch.
- Asset Life Extension: By continuously monitoring and maintaining electrical insulation systems, the operational lifespan of assets can be significantly increased.
- Compliance and Safety: Adhering to international standards (like IEC 60270 and IEC 60034) through PD testing helps ensure regulatory compliance and workplace safety.
