Kerala State Electricity Board [KSEB] — Under Voltage at home

Address:

Thattampurampady, Rayamangalam P.O, Kuruppampady, Ernakulam, Kerala, India

I've been experiencing undervoltage in the KSEB connection provided in my house. This has been happening for long time nowadays. During the night the voltage drops to around 190V and during the day it is around 200V. I am attaching relevant video and photos of the under voltage that is recorded in our meter with this complaint.
