【Abstract】 In this paper, a new instrument developed to detect the power equipment in DC system is introduced. The instrument mainly has two functions, which are the detection of the voltage of DC power and the leak current in DC circuit. On the basis of the magnetic modulation principle, the instrument can work without cutting the power of the branch circuit and influencing the working state. It can automatically measure the voltage of every accumulator and the leak current of each branch circuit. Whenever the value of the voltage is too low or the leak current is too large, (which means that Ground Fault has happend,) the instrument will alarm and show some information immediately.更多还原
