HR-CX series microcomputer harmonic elimination device is my company in the 66KV, 35KV, 10KV, 6KV, 3KV and below voltage of neutral point ungrounded or by resistance, arc suppression coil grounding system, because the ferromagnetic resonance of voltage transformer and frequent ( PT ) burn even explosion malignant accidents, a intelligent newly developed production of harmonic elimination device. The device uses the80C196 microcontroller as the core element detection, control, with high power, no contact element elimination, with liquid crystal display ( LCD ), signal lamp, micro printer ( optional) as human-computer interface, with the most advanced intelligent software, making the operation more simple, more intuitive, more accurate.

The device can real-time monitor and display the voltage component PT open delta voltage 17Hz, 25Hz, 50Hz, 150Hz four kinds of frequency, failure can quickly start, over-voltage, and can distinguish ferroresonance and single-phase grounding alarm signal is given, the corresponding; as is the resonance fault, can quickly start the harmonic elimination device harmonic elimination; and is equipped with a communication interface to transmit the fault information to the relevant departments, to realize the remote control.
