On the way to compare the polarity reversal withstand capability of HVDC mass-impregnated and extruded cable systems
​The reversal of voltage polarity is essential in HVDC cablesystems with Current Source Converters (CSC), since it enables to revert the direction of the power flow. Mass Impregnated Non-Draining (MIND) cables are known tobe able to withstand the voltage polarity reversal without particular problems. TERNA, the Italian Transmission System Operator (TSO), has introduced since many […]

Optical PD detection in high voltage cable accessories
Optical partial discharge detection is a new method to perform diagnosis of the insulation system detecting optical signals which are coming up at the same time.This method does not work with the electrical signals which are caused in case of partial discharges though. On the basis of this different physical process, external electrical noise can […]
