The invention discloses a transformer standby method based on state monitoring and reliability criteria. The transformer standby method mainly comprises the following steps: 1) obtaining transformer data; and 2) calculating the transformer aging index. And 3) calculating the number of decommissioned standby transformers in the planning time period t and the in-place time of all the transformers. And 4) calculating the total failure rate of the transformer in one period. And 5) calculating the probability that the transformer is in the mth failure state within one period. And 6) calculating thereliability level of starting the yth standby scheme by the transformer within the planning time period t. And 7) calculating the in-place time of the optimal standby scheme and the number of transformers which fail to be standby within the planning time period t. According to the method, the actual state of the transformer can be accurately evaluated by fully utilizing the actual measurement data of the state monitoring
