Voltage Stabilizer And Voltage Relay This is a Home Appliance Protection From Voltage Dips

To the best of this or that reason and circumstance, the voltage may be unfavorable for household appliances.

This can be: a break in zero in a three-phase circuit, an overloaded transformer substation, outdated power lines. As a consequence, in your electricity network instead of the prescribed 220 volts (plus - minus 10%), there may be an increased voltage (380 volts for example) or a lower voltage (170 for example). In such unfavorable conditions, household appliances either "refuse" to work or fail.

Prevent the negative impact of such factors on household appliances can be by installing a voltage regulator or voltage relay.

Voltage stabilizer is an electrical appliance that stabilizes the input voltage of the mains (increased or underestimated) and produces stabilized voltage (the output voltage range depends on the stabilizer model) in our consumer network, but in any case within the permissible deviation. Household appliances connected to the stabilizer will work stably and reliably, regardless of the input voltage. The stabilizer is used, as a rule in country houses, in the regional districts. The input voltage range and the power of the stabilizer are selected individually. For this, it is necessary to call an electrician who will calculate the total power of the connected electrical appliances and measure the voltage in the network. Select the installation location. Defines the appropriate type of stabilizer: relay, triac or stepped.

The voltage relay is an electrical appliance that will disconnect all electrical equipment (which is connected to it) in the event of an increased or under-rated power supply in the network. Such devices are usually placed in urban apartments. Relays are single-phase (for single-phase networks) and three-phase (for three-phase networks). To select the power of a single-phase relay, it is necessary to calculate the power of all electrical appliances that will be connected through this relay. When installing a three-phase relay, not only the power of all electrical appliances is taken into account, but also their distribution in phases. Also to the three-phase relay, you need a contactor that performs the communication function, since in a three-phase relay, this is not present. The range of input voltage and response time is programmed individually, at any time and is very simple.

Installation and installation of the stabilizer and voltage relay, must be performed by a qualified electrician, at least with the 4th tolerance group.
