KGZW-130 Power Fault Detector

pengenalan produk
Power quality refers to the quality of AC electric energy supplied to the client through the public grid, which is generally referred to the good or bad situation of electric energy in the grid line. The power quality problem is mainly caused by the terminal load side. Sebagai contoh, the impact reactive load will cause the power grid voltage to fluctuate sharply, reducing the quality of power supply.
Apabila kualiti kuasa grid kuasa terganggu atau tercemar, dan tidak boleh mencapai standard kebangsaan yang berkaitan, adalah perlu untuk meningkatkan kualiti kuasa grid kuasa dengan cara yang disasarkan. In order to understand the actual situation of power quality in the power grid, adalah perlu untuk mempunyai peralatan yang sepadan untuk menguji dan menganalisisnya. Memandangkan keadaan sebenar di China, our company has developed a professional KGZW-130 flat panel power quality analyzer suitable for the national conditions in time.
