Strange Electricity Spikes

[dudleynyc]

I have a 60 bottle Haier wine refrigerator. When the compressor cycles on, there is a very brief spike about 5x the magnitude of the running draw. I have no reason to believe this is anything other than the inrush current associated with starting the compressor. I’ve assumed it’s either due to this being a 16 year old inexpensive Chinese made device and/or the relatively small compressor size (about 170W when running.) I haven’t seen this with any other compressors (either identified devices, such as my A/Cs or unidentified devices, such as my Liebherr refrigerators) . In fact, the wine fridge was the very first device Sense identified, presumably due to the more unique signature.
