Can a differential machine operate on a voltage drop?

Konstantin asks:
Hello! In a private house, a voltage stabilizer is installed. After it are located 4 machines:

The first machine 25A is a 1.5 kW woodworking machine.

Second automatic 25A - A pair of sockets + lighting (no more than 4 lamas) + DIFavtomat 16A.

DIFavtomat 16A - Lighting in the bath.

Third machine 25A - Sockets lighting in the house.

Fourth machine 16A - washing machine.

When the machine is turned on, the output voltage stabilizer shows a second voltage drop, then stabilizes again at 220V (the input voltage to the stabilizer always walks in the region of 230-240V) at the same time, the differential automatic machine is activated. Then you have to turn on the Difavtomat, while the machine continues to work. By the button, the DIFavtomat test works correctly.
Does the voltage drop affect the operation of a differential automatic machine or are there other possible causes of the operation?

The answer to the question:
Hello, the voltage drawdown should not affect if you have an electromechanical differential. If electronic - then a failure in the operation of electronics is quite possible. It is not clear what your machine is connected to? I understand that he is connected to one group, and the differential works in another group?

    Alexey, I have a difavtomat like this - Differential circuit breaker AD12M 2P S16 30mA IEK.
    The machine is connected to one group, and the difavtomat to another group. For clarity, I drew a diagram.

    This is an electronic differential, maybe I'm right in what I wrote above. If possible - try to put an electromechanical one.
