MRD-KCX type microcomputer away harmonic device A, this device MRD-KCX type microcomputer away harmonic device is our company for 66 KV, 35 KV, 10 KV, 6 KV, 3 KV and below the voltage level non-ground neutral or the resistance, coil of arc extinction grounding system, because the ferro resonance and frequent voltage transformer (PT) burned the malignant accident even explosion, the newly developed and produced a kind of intelligent away harmonic device. This device using 80 C196 single-chip microcomputer as the test, control of the core components, the high power, non-contact components away harmonic, with liquid crystal display (LCD), signal indicator, the micro printer for human-computer interface, match with the most advanced intelligent software, so that the operation more simple and more intuitive and more accurate. This device can be real-time monitoring and display PT open delta voltage 17 Hz, 25 Hz, frequency 50 Hz and 150 Hz four frequency voltage component, is at fault can be quickly start, and can be the difference between over-voltage, ferro resonance and single-phase grounding, and gives corresponding alarm signal; If resonance fault, but newsletter
