New types of electrical equipment can spread different types of currents, frequencies and waveforms that are not currently measured according to current standards. Therefore, the standard must be updated, according to an ongoing research project on residual current device at Luleå University of Technology. Residual current device in photovoltaic systems can be adversely affected and become a safety risk.
Researchers and students at Luleå University of Technology have developed a handheld tool to make it easier to measure snow properties in the field. "The portable monitor is developed to be able to compare snow on different test tracks," says Johan Casselgren, associate professor of experimental mechanics at Luleå University of Technology.
The commissioned education in operation and maintenance technology for foreign-born engineers developed by Luleå University of Technology in collaboration with the Swedish Public Employment Service and Northvolt has now started.
