Remote monitoring method for energy metering error resulting from impact load

The invention provides a remote monitoring method for an energy metering error resulting from an impact load, and belongs to the field of electric power equipment. The remote monitoring method includes the steps of initializing a remote monitoring host, selecting a preset range, and connecting the processed remote monitoring host to a power supply to be detected; enabling the remote monitoring host to sample test electrical signals output by the power supply to be detected after the analog-digital conversion processing, obtaining a calculation result according to a sampling value and comparing the calculation result with the preset range; and performing a different processing mode according to the comparison result. The remote monitoring method can accurately obtain a parameter value of the electrical signals output by the power supply to be detected by selecting the preset range of the remote monitoring host and comparing the calculation result obtained by combining the sampling value with the preset range,
