The light blinks when a powerful load is turned on - what to do

Good afternoon light blinking in all rooms? Does it blink like when the load is turned on, and then it starts to shine normally or the brightness sags until you turn off the load?

I believe there is a connection or small gauge problem in your wiring.

If we talk about the input, then under the normal state of affairs, such strong drawdowns should not be when a 2 kW load is connected. And it can be either with poor contact of the wires of the overhead power line (or rather, the branch to the house), also with their small cross-section, well, or the cross-section of the branch to your house. Do you live at the end of the line and far from the substation?

If so, then nothing can be done about it. Moreover, when you connect the load through the stabilizer, at a reduced voltage, the current is consumed even more, respectively, the drawdowns at the input will be stronger. What were the drawdowns before the stabilizer was installed?

With all of the above, I will add that the light may blink due to the speed of the stabilizer. Relay stabilizers are not the fastest, the electronic stabilizer (thyristor or triac) works faster.

But I will add that when the load is connected, it may blink due to poor wiring, i.e. drawdowns somewhere on the twists inside the house, i.e. after the stabilizer, occur.
