Reverse Active Power Protection (ANSI 32P)
Reverse power relays are used to detect the failure of the prime mover (engine) when active energy (Watts) flows into the generator causing rotation - the set will operate like an electric motor, which can cause significant mechanical damage. In 2012 IEEE International Power Engineering and Optimization Conference (PEOCO2012), Melaka, Malaysia: 6-7 June 2012 Protection against overload is crucial in setups where the prime mover is . These devices can protect equipment from damage caused by excessive current or phase imbalances, and they are used in a variety of different settings including factories, power plants, and even residential homes. This condition normally occurs when the prime mover (engine or turbine) fails, however the field winding is still connected with the excitation system. The quality of this series of products is stable and reliable, and the technical performance meets the relevant requirements of CCS specification.
