Abstract (en)

[origin: WO2020170142A1] An load monitoring apparatus for monitoring an electrical apparatus, the load monitoring apparatus comprising a controller(142) which is configured to capture and process voltage and current data of the electrical apparatus, which is electrically connected with a power supply, to obtain electrical parameters of the electrical apparatus, to store the electrical parameters as measured electrical parameters, to compare the measured electrical parameters with a set of pre-stored electrical parameters, to determine whether the measured electrical parameters match with the stored electrical parameters, and to operate a power switch to turn off power supply to the electrical parameters if the measured electrical parameters do not match with the stored electrical parameters.
