(author), Lahti, Kari (author), Khamlichi, Abderrahim (author), Arcones, Eduardo (author), Klüss, Joni (author), Mor, A. R. (author)On-site partial discharge (PD) measurements have turned out to be a very efficient technique for determining the insulation condition in high-voltage electrical grids (AIS, cable systems, GIS, HVDC converters, etc.); however, there is not any standardised procedure for determining the performances of PD measuring systems. In on-line and on...journal article 2023

Mier Escurra, C. (author), Mor, A. R. (author), Vaessen, P.T.M. (author), Lathouwers, A.G.A. (author)One of the main difficulties in measuring partial discharges (PD) in gas-insulated substations (GIS) is the overlapping of pulses at the sensor's location, which distorts the pulse resolution and the charge estimation. This research presents a new method called “synergy,” which identifies and suppresses reflections using magnetic and electric...journal article 2023

Mier Escurra, C. (author), Khamlichi, Abderrahim (author), Dalstein, Matthieu (author), Vidal, Jose Ramon (author), Garnacho, Fernando (author), Mor, Armando Rodrigo (author), Vu-Cong, Thanh (author)Driven by the voltage increase in high-voltage direct current (HVDC) gas-insulated substations (GISs), novel methods are needed for partial discharge (PD) detection and monitoring. This article shows a PD calibration method for very-high-frequency (VHF) magnetic and electric sensors in GIS. The calibration method uncertainty is tested in...journal article 2023

Mier Escurra, C. (author), Mor, A. R. (author), Vaessen, P.T.M. (author)A recent investigation explored a new measuring concept used in partial discharges (PD) measurements in gas insulated substations (GIS), consisting of a magnetic loop antenna. The sensor's frequency response was characterized up to some tens of MHz. This paper proposes an improved version of the sensor with an extended bandwidth (BW) one...journal article 2021

Mor, A. R. (author), Castro Heredia, L.C. (author), Muñoz Muñoz, F.A. (author)This paper presents a novel measuring system for partial discharge (PD) measurements in Gas Insulated Systems (GIS) using high frequency current transformers (HFCT). The system is based on the measurement of the induced PD currents in the GIS enclosure. In opposition to the existing antenna technologies that measure the radiated energy in the...journal article 2018

(author), Bauer, P. (author)A scientific consensus is emerging on the benefits of direct current (DC) distribution in medium voltage (MV) power systems of ships and cities. At least 50% space savings and increased power transfer capacity are estimated with enhanced voltage DC operation of electric cables. The goal of this research is to contribute to developing the...journal article 2017

(author)In addition to after-laying of new-installed high voltage (HV) power cables the use of on-site non-destructive on-site testing and diagnosis of service aged power cables is becoming an important issue to determine the actual condition of the cable systems and to determine the future performances. In this paper based on field experience an...journal article 2008
