  1. 1. Improving maintenance scheduling with condition monitoring on the electric distribution grid : An economic analysis comparing corrective and predictive maintenance

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Hugo Vincenti; [2022]
    Keywords : Condition-based maintenance; predictive maintenance; health index; failure rate; maintenance scheduling; sensors; economic analysis; simulation; Tillståndsbaserat underhåll; förebyggande underhåll; hälsoindex; felfrekvens; underhållsplanering; sensorer; ekonomisk analys; simulering.;

    Abstract : A growing use of sensors on the electric grid has opened the door to new methods of asset management: Distribution System Operators are now looking into conditionbased maintenance, as opposed to the traditional corrective or time-based methods. As an emerging field, the methodology must be constructed from the ground, with the little data available. READ MORE

  3. 2. Enhanced dielectric AC breakdown strength of polyethylene using voltage stabilizing additives

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Klas Esbo; [2016]
    Keywords : cross-linked polyethylene; LDPE; low density polyethylene; polyethylene; voltage stabilizing additives; fast avalanche breakdown; dielectrical breakdown strength; High voltage cable; HVAC; XLPE; Weibull distribution; AC breakdown; materials chemistry; materialkemi; Technology and Engineering; Chemistry;

    Abstract : There is currently a need to increase the voltage level in high voltage transmission and distribution systems in order to transmit power in a more efficient way. However, the insulation of the conductor in high voltage alternating current (HVAC) cables needs to be improved in order to withstand these high voltages. READ MORE

  4. 3. Experimental analyses on XLPE under tension and compression

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : faranak pirnia; [2014]
    Keywords : XLPE; stress relaxation; compressive; tensile; visco elastic models; Young modulus stress.;

    Abstract : Cross linked poly ethylene used in high voltage cables insolation, has been studied to define its mechanical behavior. Time dependent deformation tests (stress relaxation) in three different strain levels and normal compressive and tensile tests were carried out. READ MORE

  5. 4. Conductivity measurement on thick insulating plaque samples

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Pierre Huldén; [2014]
    Keywords : Conductivity; XLPE; leakage current; polarisation; high-voltage; ICE 60093; ASTM;

    Abstract :   The conductivity is one of the main properties of HVDC cable insulation materials and needs to be evaluated carefully. Since measurement on cables is time consuming, often thin specimens and normal conductivity measurement cells are used to compare the materials. READ MORE
