This research project studies the issues associated with 22 kV XLPE underground cable systems by utilizing polarization and depolarization current analysis, a modern insulation diagnostic method, to address operational challenges in modern urban power grids.
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 and developing testing and analysis techniques for electrical insulation using polarization and depolarization current measurements.
- Study the issues associated with underground cable usage.
- Study testing and analysis techniques for electrical insulation using polarization and depolarization current measurements.
- Develop testing and analysis techniques for underground cable problems by analyzing polarization and depolarization current measurement results.
