It's virtually certain it is not the power grid with that 
pattern. Things like fish tank heaters and other heating 
devices with thermostats that open the power line, door bell 
or other small transformers tripping an internal thermal 
breaker, electric fences, some chargers, and so on have 
cyclic patterns.
