A Water Absorption Chamber Design for Cable Capacitance Measurement Tests

XLPO cables used in ships should be tested for water absorption. Test standards require the cables be submerged in a water absorption chamber and kept at 75 0C for 14 days. Once every 7 days, the cables within the chamber are tested by applying high voltage, and their capacitance, dissipation factor, stability factor, and relative Permittivity are measured. In this study, a water absorption chamber used in the experiments is designed using fiberglass material and controlled with an ENDA ET 4420 temperature controller. It is experimentally shown that the water absorption chamber performs well.
