INTRODUCTION


RARA manufactures load banks, ranging from small portable units for testing generators to multi-megawatt designs for larger applications.  Regular load testing, along with correct battery maintenance, is the best way of ensuring the reliability of standby power systems.  For many years it has been routine for all newly-installed generating sets to have a load test during the commissioning process in order to prove the performance of the set and all its ancillaries – cooling system, exhaust system, switchgear and protection schemes.
 

-custom designed for your particular system
-several stages of assembly depending on shipping needs
