HPD300 generator reverse power protection

HPD300 reverse power protection relay is widely used in marine genset field and land genset field. The power direction, instead of flowing predominantly generator to Bus as usual, flows backward to generator from current system when generator lost excitation or other failure occurs. That is to say, generator works as electromotors. HPD300 reverse power protection relay is to avoid the above situation and provide protection when over power situation occurs
