Unstable voltage in my hostel

Unstable voltage in my hostel


At 14:19, there was 2 sec, that my 21W T5 dimmed considerably than brightened up. I opened my UPS shutdown software and viewed the log only to see the voltage at 191.6V during this period. It soon becomes clear by my Osram/Ledvance LED filament lamp, that the voltage in my hostel is unstable (This is still not a brownout), and once per min, drops down from ~210V to ~195V for several sec and back to 215V, which is expressed by the LED filament lamp dimming considerably and flickering than instantly brightening up.

Here is a video that explains that .
