Condition Assessment of Medium Voltage Cable Accessories - PD Measurements at Variable Frequencies
Einan, Gunnar Stokke (Master thesis, 2016)Diagnostic PD testing of medium voltage cables can be performed at very low frequencies (VLF, 0.1 Hz), to reduce capacitive currents. At 0.1 Hz the field distribution in the field grading materials is likely different from ...
