UHF PD Diagnosis at high voltage cable terminations
High voltage terminations are essential components in high voltage cable systems. Great reliability is provided by high manufacturing quality and company type testing. However, onsite installations represent a considerable uncertainty for successful service of the system. UHF PD Diagnosis has proven to be a valuable and effective method for measuring high voltage assets because this online measurement is performed at frequencies which are not affected by environmental noise.
