The Industrial Applicability of PEA Space Charge Measurements, for Performance Optimization of HVDC Power Cables

2019

Cable manufacturing industries are constantly trying to improve the electrical performance of power cables. During the years, it was found that one of the most relevant degradation factors influencing the cable lifetime is the presence of space charge in the insulation layer. To detect the accumulated charge, the pulsed electro-acoustic (PEA) method is the most used technique. Despite the wide use of the PEA cell, several issues are still present. In particular, the PEA output signal is strongly disturbed by the acoustic waves reflections within the PEA cell. This causes the distortion of the output signal and therefore the misinterpretation of the charge profiles. This, in turn, may result…

Effect of Space charge accumulation inside the thermoplastic insulation of a loaded HVDC model cable

2021

The space charge accumulation phenomenon represents one of the main degradation factors for the dielectrics employed in the field of the HVDC transmission. For this reason, the recommendation IEEE Std 1732-2017 has been proposed. In that standard, due to the importance attributed at the space charge phenomenon, the experts suggest the introduction of the space charge measurement in HVDC cables during the prequalification or type tests, by means of the PEA method. However, despite for tests in flat specimens the PEA technique is well consolidated, for cable specimens difficulties are still present. In particular, the PEA cell output signal is strongly conditioned by the arranged measurement …
