High temperature epoxy resin bushings for windfarm transformers

Turbine designs continue to grow in power size, while reducing the space provided for the transformer in the nacelle area. This presents several challenges in transformer bushing designs, one of which is the considerable increase in the ambient temperature. As a result, H-J has developed a new high-temperature epoxy used on transformer bushings to help […]

High-performance visibility measurement

Wind energy is one of the forefront sources society has come to depend on as a clean energy solution. Of course, there are always challenges when it comes to implementing new solutions. Wind turbines are a key component of wind energy generation but are known to have some drawbacks that make them less desirable to […]

The sun as a natural power plant

Powerful vacuum technology and reliable tightness control for improved efficiencies of solar receivers When solar energy for electricity generation is discussed, photovoltaic systems most often come to mind. However, concentrated solar power systems are gaining popularity as an interesting alternative. In this type of power plant, collector systems concentrate sunlight and collect it on an […]

Bifacial solar modules: how to measure them in production

Abstract Bifacial modules are entering the large-scale solar installation market. This article briefly describes the technology behind bifacial modules and focusses on what is needed to measure them with a sun simulator to show the extra power gain they provide. The procedures described here are based on the Technical Specification IEC 60904-1-2:2019, touching also on […]

Modernizing control system for absolute cavity radiometer

Accurate measurements of broadband solar irradiance require radiometers with proper design and performance characteristics, correct installation, and documented operation and maintenance procedures, including regular calibration. With any measuring tool, calibrations must be traceable to a recognized reference standard. For direct normal irradiance (DNI) measurements of broadband solar radiation, the World Radiometric Reference (WRR) is the […]

A giant with a brain

Smart turbines: embedded intelligence is the next engine growth factor for the automotive industry. Specialists estimate that in less than 10 years, the software element will represent 60% of the value of a vehicle, compared to 20% today. When you think about the pace of change in the wind industry today, we can expect a […]
