Impressive accuracy

This was the first accessory I bought after buying my fifth wheel RV. I have a pad to park my RV on while at home complete with a 50 amp receptacle. I keep it plugged in during non use times because of the residential fridge and to keep the batteries charged. I have a surge monitoring system in my home and my voltage is extremely stable. Because of the distance, mine is the only house on the transformer. I got a notification on May 8 that my voltage had surged to 132.8 volts and apparently remained there for 12 minutes. I hadn't been in the RV for several days until yesterday. I noticed the clock on the microwave was flashing like there had been a power outage. The Surge Guard had apparently sensed the surge and opened the circuit. The 132.8 volts (if accurate) is only 0.8 volts above the +10% tolerance level; that's extremely accurate! I have always had a high degree of confidence in the Surge Guard; now my confidence level has risen to extreme level of confidence!
