Dump load trouble detect system and trouble detect method

The present invention relates to a dump load fault detection system and fault detection of the hybrid power system method, in a system for detecting a failure of the dump load being provided in the hybrid power system, one end connected to the power line and supplies a current to the dump load and a shut-off switch to the one end connected to a said switch in series and the other end dump load connected to the ground and which is connected to the contact forming the middle and one end connected to the power line and the first resistor and one end of the second being connected in parallel with the switch, a third resistor and one end of said through to first resistor in series and the other end is connected to a connection contact of the second resistor and the one end of the dump load connected to the switch and the contacts of the dump load being connected in parallel with said dump load claim by a fourth resistor connected in series with the third resistor and the other end connected to said ground , To find out the error of its own dump load short-circuit or disconnection of a safe manner and can implement them dump load fault detection system that administrators can easily identify.
