I just got one. A long one. More like a brownout. The power company sent a higher voltage into the 11Kv transformer, and that cooked it. So now, it is sending 50-60v to every house in my neighbourhood. I measured with the multimeter and it shows anywhere between 50-60v ac. Things like my WiFi are working, but no light no fan. The stabilisers on my refrigerator and air conditioner are struggling a lot to get 60v into 240v.
Wish me best of luck, I'm trying to depend on cold breezes to stay cool in the summer afternoon (it's really hot here)
How your Wi-Fi works? Routers have a switching power supply which is usually 100-240V, so at 50-60V I don't expect it to be work.
I've a battery backup for my Wi-Fi router, so it can operate during power failures.
