electrical distribution system through properly sized electrical feeder 145 and corresponding circuit breaker 150 the electrical power output of orc system 130 is monitored by electrical active power transducer 155 and the resulting data is transmitted to controller 90 the purpose of power transducer 155 is to function as a protective device different protection levels can be set for example in case of excessive power being generated by the system controller 90 can be programmed to reduce the speed of exhaust gases fan 60 in order to reduce the heat transferred or to stop the operation of exhaust gases fan 60 completely under pre designated circumstances some commercially available orc systems also incorporate a by pass valve for the heat source fluid as a protection in the event an upstream electrical interruption occurs such as through tripping of a circuit breaker and generator 140 is disconnected from the distribution network protection would also be required in this case active power transducer 155 will indicate zero power and a stop exhaust gases fan 60 sequence will also be initiated if the liquid pressure exceeds a predetermined certain value detected by third sensor 125 the target reference of first vfd 70 for exhaust gases fan 60 will be reduced as a measure to slow down the heat transfer that could be contributing to high pressure in the event of sensing of a predetermined greatly excessive pressure pressure relief valve 110 will actuate and the corresponding signal.
