The present invention relates to an apparatus and method for detecting a DC ground voltage and supplying trip power. According to one aspect of the present invention, provided is the apparatus for detecting the DC ground voltage of a circuit breaker and supplying the trip power which includes a DC ground voltage detecting unit which detects the level of the DC ground voltage and generates a ground level detection value, a control unit which compares a set value with the ground level detection value and activates a control signal by detecting a ground, and an output unit which supplies the trip power in response to the control signal. According to the present invention, an accident due to the ground is prevented by tripping the circuit breaker by operating a trip device by supplying the trip power to the trip device according to a comparison result after the ground level detection value is compared with the set value. [Reference numerals] (10) Unit for converting the voltage and generating the power; (20) Output unit; (30) Control unit; (40) DC ground voltage detecting unit; (50) Setting unit; (60) Display unit |
