Protecting the power network from electrical faults

Electricity is transmitted at high voltages (HV) and reduced for domestic use by power transformers installed in HV substations. Many substations are located inside buildings in urban areas in reduced spaces. HV switchgear, such as circuit-breakers and disconnectors, are used to de-energise equipment to allow safe maintenance. ...

Ensuring the applicability of tests for high voltage networks

Between 0.5 to 3% of all electricity injected into European power grids is lost during transmission. To reduce this network operators are transitioning from high voltage alternating current (HVAC) to high voltage direct current (HVDC) as it is more efficient in transporting electricity and also offers compact overhead lines, un...

Metrology to protect the high voltage grid

Electrical losses are one of the main contributors to operational costs in power networks. To minimize this network operators are transitioning from high voltage alternating current (HVAC) to more efficient high voltage direct current (HVDC). Partial Discharge (PD) measurements, detailed in the international standard IEC 60270,...

Faster solar cell product development

Multi-junction solar cells (MJSC) are made up of layered semiconductors that, together, absorb a wider range of solar energy than silicon alone. Higher energy conversion efficiencies for this type of cells are predicted, that, in time, may enable photovoltaics to become cost-competitive with conventional energy sources. Manufac...

Ensuring biogas quality for gas grids

Biogas production and its upgrade to biomethane have the potential to reduce Europe’s dependency on imported natural gas. In 2017, 65 000 GWh of biogas generated electricity and 18 000 biogas plants contributed to energy supply diversification. Biogases are produced by digesting a variety of industrial waste streams high in org...

Improved nuclear incident data analysis

High-speed digital data acquisition enables the direct observation of sensor outputs - a major advantage over conventional instrumentation. More compact and less power hungry, the use of this technology in mobile applications is increasing. For example, first responders at major nuclear incidents can check surroundings for cont...
