1、Register accurately electric power measurement circuit loss time, calculate the corresponding lost power: in the current condition of load, electric power measurement voltage circuit loss time (one phase, two phase or three phase), accurately accumulated loss time, calculate the corresponding lost voltage lost power amount, indicate the disconnection phase difference, carry out loss voltage alarm, until the voltage recovery;

2、Register accurately loss of voltage failure status and time: When one phase, two phase or three phase loss of voltage, record separately beginning (below the rated voltage) when one phase, two phase or three phase loss of voltage, record separately starting (below the rated voltage) when one phase, two phase or three phase loss of voltage, record separately starting78%), tɛmɛ (ka dɔɔri ka tɛmɛ voltage)85%(Time) ye kaam ye kaam ye kaam ye kaam ye kaam ye kaam ye kaam ye kaam ye kaam ye kaam ye kaam ye kaam ye kaam ye kaam ye kaam ye kaam ye kaam ye kaam ye kaam ye kaam ye kaam;
