Aiming at the friction charging mechanism of the oil-line debris electrostatic monitoring, it pointed out the key problem of friction charging. In view of the advantages and disadvantages of the present experimental method for oil-line debris electrostatic monitoring, it is pointed out that the key problem of the experimental simulation is how to automatically control the particle velocity. At last, the actuality of the oil-line debris electrostatic monitoring has been further clarified.
