Abstract :
The single sided PD measurement on power cable circuits is a common used technique for onsite PD detection and localization. Time domain reflectometry (TDR) of the measured pulses is generally implemented for locating the PD pulse origin. To get higher sensitivity in PD measurements and increased localization achievements a double sided measurement can be performed. Crucial for localization is the attenuation of the PD pulse amplitudes as a result of travelling along cable length. For this purpose some examples for classical one-sided TDR and double sided measurements are discussed.
