Though I'm not sure on the details of a frequency drop and impact upon your house in exacting details. Equally I'm not up on substations (did work on IT for large util company many decades ago, but not field engineering). But the first safety control from supply to the home, would be the distribution transformer and those back then had overheat protection. Also had a flag attached by wax at one spot, so if they did overheat and cut out for a while, you could visualy see that due to the flag being visible. But that was more a legacy solution that still prevailed into the 80's, unsure about now. But would not be supprised if such tried and tested things still take place as some form of backup monitoring. I learned about it after coding for a database that stored such records that had the field name SITESHIT, which was short for "SITES HIT", yes - you can see how that gave a young humble COBOL programmer a laugh. But it would be a count of how many times that wax flag had been triggered.

- pbhjpbhj 7y agoFrom that article: >"In Japan, the western half of the country runs at 60Hz, and the eastern half of the country runs at 50Hz – a string of power stations across the middle of the country steps up and down the frequency of the electricity as it flows between the two grids." // That's, err, curious.
- stordoff 7y agoIt's largely a historical artifact: > Eastern Japan (including Tokyo, Kawasaki, Sapporo, Yokohama, and Sendai) runs at 50 Hz; Western Japan (including Okinawa, Osaka, Kyoto, Kobe, Nagoya, Hiroshima) runs at 60 Hz. This originates from the first purchases of generators from AEG for Tokyo in 1895 and from General Electric for Osaka in 1896. https://en.wikipedia.org/wiki/Electricity_sector_in_Japan#Transmission https://en.wikipedia.org/wiki/Electricity_sector_in_Japan#Tr...
