br(,,): : !r , r,:(,,) b>The power quality online monitor is the most advanced technology in the world, the crystallization of microelectronics technology and manufacturing technology. This product adopts independent channel sampling and independent calculation to avoid large errors in data calculation and analysis caused by multi-channel sampling. The hardware part of the power quality online monitor has no mechanically adjustable components, so it can operate reliably and stably for a long time. It is the best product adapted to the modernization of power quality management.
