If the voltage drop in the network apartment for Macbook Pro?

Good, friends!
A question: if my Macbook Pro the voltage drop in the electrical network of the apartment?
The essence of what apartment, phase one for the whole apartment, when you start and stop the motor of the refrigerator there is a drop/increase in voltage electrician measured, it can jump from 223 to 230 (enabling/disabling). It equipment - monitor, speakers, laptop and a lamp. All connected to the new Pilot Pro. So, when you start/stop still static/clicks on the speakers. And what happens with the MacBook? He's always online with me. To interference sound can be used, they are not very frequent and used. And for the worried technique.
Thank you in advance!

Solution
well, the column is clicked is clearly not from this ridiculous jump in seven volts there at the time of starting the fridge the more exciting things edge happen...
don't worry, nothing will happen to your buck. if you saw the voltage waveform, which gives a cheap UPS which every third work... an untrained person can bring to tantrums - there is little that is not a sine but something lomano-angular, and the pulse under 400 volts (very short) skips... and nothing, lives and works equipment. Switching-mode power supply is one of the greatest inventions of mankind ))

in General, a good filter needs to be rescued. apparently the fact that you have a good filter is not. or change or just drive.
Thank You for the detailed answer! - Rosemarie_McLaughl commented on July 8th 19 at 12:02

Safe, the power supply, it is stable, for reassurance can make oscillogram output voltage and to protect against interference, use a surge protector.
So is Pilot Pro from the noise itself does not save. Ground in the sockets there. I think the filter will help if it will jump much more than I described. Thanks for the reply! - Rosemarie_McLaughl commented on July 8th 19 at 12:04
: The ground is not even in the house? Then try the zero. - Rosemarie_McLaughl commented on July 8th 19 at 12:07
: Well, with the flap of the corridor in the guard the apartment is ground. In General, outlets only a phase and a zero. To annihilate to what? - mazie.Towne commented on July 8th 19 at 12:10
To annihilate is to plug in zero as the ground, if the house is old, then the flap too not grounding, and vanishing, I even wire yellow-green, nevertheless. - Rosemarie_McLaughl commented on July 8th 19 at 12:13
: and for it do not want? - mazie.Towne commented on July 8th 19 at 12:16
No. And for what? Even so: and from whom? - Brody_Dickins commented on July 8th 19 at 12:19
Comrades, enough crap to carry. Earthing/zeroing are measures to protect from shock. To protect equipment from power quality is not affected. - mazie.Towne commented on July 8th 19 at 12:22
: Do not be rude and be careful, the ground/neutral earthing I offered not to protect against surges and interference, really helps, the noise is the AC voltage, so help network filters (there's a system of inductances and capacitors) and helps neutral earthing/grounding, at least, against interference from the sparks household motors, ignition gas stoves, etc., but from the high-frequency noise of the power supply did not help, "high-frequency" LC filter must be either in a block at the exit or in the computer. - cortez_Jon commented on July 8th 19 at 12:25
: how can I annihilate, can you describe the procedure? I just no-no. - mazie.Towne commented on July 8th 19 at 12:28
: The outlet is grounded? It is connected to some wire?
I have in the apartment at all no ground, only 2 wires everywhere, I'm at the outlet just a jumper (piece of wire) placed between the 0 and ground. - Rosemarie_McLaughl commented on July 8th 19 at 12:31
: The grounding pin in the socket mean? Two horns on the input plug? No, but I have the same can buy. In my apartment there is also grounding. Disassemble the socket, there is only a phase and a zero. Ie I buy the socket to ground, and a piece of wire to hold from zero to her? - mazie.Towne commented on July 8th 19 at 12:34
: Yes, antenna input, Yes, buy the socket to ground, and a piece of wire to hold from zero to it zero in the socket to take the sample, then how to hold the ground a separate wire. - Rosemarie_McLaughl commented on July 8th 19 at 12:37

use not every Chinese GE, and buy a normal surge protector from APC. How much you use - the most appropriate price/quality and the performance of its functions.
The Pilot extension cord is not a surge protector, and just more or less a good switch under heavy load due to the bimetallic switch and the fuse.
For filtration there is a layout on the capacitors.

p.s.: this is of course if the pilot pro, which was in the hands of a twirl, when this pro fuse.
The normal network filter costs half the price of a new refrigerator that now does - Rosemarie_McLaughl commented on July 8th 19 at 12:06
: the same APC for 1-2K rubles already know how to filter the "household" noise is normal.
Pilots are generally not designed to filter. - Rosemarie_McLaughl commented on July 8th 19 at 12:09

+-5% of 220V is the norm according to the standard. If you have a flat non-industrial or ancient Soviet refrigerator - no need to worry.
Don't know how they have MacBook, but the other notes on the power supply parameters input voltage AC 100-240V, so jump 223-230V him purple
