On behalf of Hymatek (Rainpower) I have been to Pangani Falls in Tanzania to commission two new static excitation systems (Magnostat 10S). I also supervised de-installation of old equipment and installation of new equipment.
The power plant was built in the mid 90s by Norway/Sweden (ABB and Kvaerner) and is owned by the governmental company TANESCO. It has two units, each on 40 MVA.
