For any remotely-controllable power meter, its contactor switch should have been designed to sync with the zero crossings of the AC waveform. That would have completely prevented this damage. I know it would have made the meter more expensive, but it was absolutely forseeable that a wild RF signal could have induced repeated contactor reclosings. They should have built it properly.
