PURPOSE: A portable direct current ground detecting apparatus and a detecting method using the same are provided to easily determine ground in a work field where the detection of current is difficult. CONSTITUTION: In a portable direct current ground detecting apparatus and a detecting method using the same, a signal generator(100) generates a signal current supplied to a DC transmission line. A signal detection unit(200) detects a current flowing in the DC power line through the signal current supplied to the DC transmission line. |
