This research project studies the challenges of 22 kV XLPE underground cable systems by utilizing polarization and depolarization current analysis, a modern insulation diagnostic method, to address the needs of modern urban power infrastructure.
Due to the modern urban system's high demand for stable electricity supply, underground cable power transmission has been increasingly adopted as a replacement for overhead power transmission. However, underground cable transmission still faces several operational challenges, such as:
- Significantly higher investment costs compared to overhead transmission
- Prolonged repair times in the event of system failures
- Limited fault analysis capabilities
- Restricted capacity for additional load handling
This research project is designed to study the issues associated with the 22 kV XLPE underground cable system by utilizing the polarization and depolarization current analysis technique, a modern insulation diagnostic method.
Objective
The objectives include studying underground cable operational issues, exploring insulation testing techniques, and developing diagnostic methods using polarization and depolarization current analysis.
- Study the operational problems of underground cable systems.
- Study testing and insulation analysis techniques using polarization and depolarization current measurements.
- Develop testing and diagnostic techniques for underground cable issues by analyzing polarization and depolarization current measurement results.
