December 2016, Yukon Energy awarded the replacement of its Whitehorse 4 static excitation system to Reivax North America. Reivax North America has manufactured and delivered its RTX Power excitation system to the Whitehorse hydro station of Yukon Energy on April 2017. Yukon Energy will install the system and Reivax North America will commission it in June 2017. Reivax designed and built a special cabinet for the static excitation system in order to mimic the cabinet of the previous system. This solution is facilitating the installation of the Reivax excitation system with the existing power and control cables that are being re-used. The excitation system is rated for a maximum continuous current of 1,400ADC.
