This is exactly what the title of the question from the reader Eugene sounded like.
I continue to publish the questions that readers asked me. For new dear readers who came to my channel for the first time, I inform you that this is already 17 such publication.
Consider the question from Eugene in this 17th part:
Good day. Tell me please. I have a low voltage in my house every day, the barrier is often turned on and off at 169 volts. What solution can be found for voltage stabilization?
I consulted Eugene within the framework of my knowledge and qualifications as follows:
I understand that the barrier is a voltage monitoring relay? In this case, it is quite natural that it is triggered when the supply voltage drops below the set limit. This is done in order to prevent the failure of a certain category of electrical equipment due to a mismatch in the quality of the supplied electricity.
Typically, this problem occurs in areas where the load on the supply transformer significantly exceeds the permissible power limit. To solve the problem within your home, I recommend installing a voltage stabilizer. Which is selected individually, depending on the parameters of your home electrical installation and the planned budget:
- Stabilization power - determines the permissible load for which the converter can increase the voltage to the set limit. If this indicator turns out to be too low, the stabilizer simply cannot cope and turn off.
- Number of phases - a single-phase model is suitable for a classic house, but if a three-phase network is suitable for the house, a three-phase stabilizer is selected.
- Stabilization type - relay, servo and electronic. Relay models are older, but also some of the cheapest. Servo and electronic ones differ in a more modern switching principle, but also at a higher cost.
On a global scale, you can file a complaint with the management company to have a more powerful transformer installed in your area or to analyze the phase load of an existing transformer. For the best effect, issue a collective letter with a copy to local authorities.
P.S. Dear Readers! If you have your own version of the answer to this question, please write it in the comments. It will also be interesting for me to read it and, if necessary, discuss it.
P.S. Link to some past parts - Part 16, Part 15, Part 14, Part 13, Part 12.
