Failure risk assessment method of electric energy meter based on state evaluation

Comprehensive evaluation the operation state of electric energy meter, put forward a kind of electric energy meter failure probability calculation method. Based on the state evaluation to the electric energy meter, the evaluation results and the failure statistics is associated, through inversion calculation correlation coefficient, fitting the failure probability curve of electric energy meter. Examples of calculation indicate that the failure probability is basically in line with the actual situation of the equipment performance, it's a effective method for estimating the apparatus's failure probability in the current operating state, data support is provided for the quantitative risk assessment of electric energy meter.
