Residential voltage monitoring relays
Now, it has become quite common practice to install a voltage monitoring relay in the residential sector to protect electrical equipment from zero breakage, from over and under voltage.
On Instagram and YouTube, you can see that many of my colleagues are experiencing problems in this area, after installing the voltage control relay from Meander, and some other manufacturers that very often fail, my colleagues have to change them, mostly change to the same ones. and everything repeats again.
Video about defective products Meander of one of my colleagues: Marriage UZM 50ts, replacement .
Many are now puzzled by the choice of the equipment of which manufacturer to use, although the answer has always been obvious, it is best to use equipment from manufacturers such as Siemens, Schneider Electric.
I want to share my experience and reliable solutions that I use in the residential sector here.
Three-phase voltage monitoring relay Schneider Electric Zelio Control .
Parameters controlled by relays:
Lack of neutrality.
High and low voltage phase-phase.
Over and under phase-zero voltage.
Load switching by means of a contactor KEAZ PM-12 250 A.
Switching the coil of the contactor KEAZ PM-12 250 A through the contactor KEAZ PM-12 16 A.
Relay of control of tension single-phase Schneider Electric Zelio Control .
Parameters monitored by the relay: detection of overvoltage and undervoltage.
Load switching via a contactor modular Schneider Electric TeSys 63 A.
I also want to note the silent operation of the Schneider Electric TeSys modular contactor.
This article is not an advertisement, I use Schneider Electric products, as ABB has a large number of defects, and Siemens is much more expensive in terms of cost and longer in terms of delivery.
