Problems solved by technology
However, at present, only meter-type voltmeters and ammeters are used in cabinets such as GCS and GGD, and it is impossible to obtain data more accurately, and the data is not analyzed and calculated for power harmonics, and the inductive and capacitive properties of the subsequent stage cannot be guaranteed. The operation stability of the load, this traditional operation and maintenance and detection method has high requirements on the cost, and is not conducive to maintenance and prediction of danger in the power distribution room
