Resumen
The amount of electricity generated from renewable sources needs to increase to meet
the EU's aim of becoming carbon neutral by 2050. However, the connection of renewable
sources to the power grid causes harmonics which lower network power quality and
increase electricity losses in e. g. , power transformers and high voltage alternating current
(HVAC) cables. The industry thus requires new HV metrology tools to monitor the
increased level of grid harmonics, as well as instrumentation to quantify the impact of
these harmonics on the efficiency of power transformers and HV cables, next to new
methods to evaluate the reliability of high voltage direct current (HVDC) grid connections.
Therefore, this project will develop new 1) wideband live connectable current or voltage
sensors to monitor and calibrate substation instrumentation, 2) capabilities for determining
the power transformer losses that are caused by grid harmonics, 3) methods for
determining harmonic losses from HVAC cables, and 4) partial discharge (PD) monitoring
techniques for fault detection and location in HVDC cables.
