Abstract
In order to resolve the problem of hidden trouble about safety in existing capacitiance current measurement device, the paper put forward a design scheme of on-line measurement device of capacitance current based on DSP, introduced the measurement principle, design of hardware, and software of the device.The device uses the signal-injection method to measure capacitance current of power network which uses arc-suppression coil to on-line inject signal range from 20 Hz to 80 Hz with step 0.2 Hz and equal amplitude into secondary side of arc-suppression coil, uses DSP to process feedback signal to get resonate frequency of power network system, then indirectly gets capacitance current. The device solves the problem of safety of mesuring capacitiance current.关键词
