Brushless exciter system RK 12014

for alternator

Exciters associated with the rotating rectifier bridge The current generated by the exciter must be rectified to be injected into the polar wheel of the main alternator, it's the job of the rotating rectifier. It consists generally of 6 diodes and can be equipped with over voltage protection or other safety devices. Optimum reliability is obtained by use of a rectifier equipped only with diodes. Exciter stator is fed by a voltage regulator. Exciters for Hydro-electric Power Stations : The majority of hydro-electric power stations were built before 1970. Today with new technologies, these power stations can increase their production of energy by 20% by renovating the unit harnesses alternator. The infrastructure is preserved, this relatively inexpensive solution is used worldwide. With these modifications, the exciter system easily be modified to brushless system. EMG-EMCO is one of the few companies worldwide who can offer the transformation of these original exciters to brushless exciters by re-using the original magnetic circuit thus cutting costs. EMG-EMCO have already renovated any power stations worldwide.
