Voltage regulators are devices that make power supply parameters that are not up to standards to comply with set quality parameters.
Lately many devices sensitive to power quality are designed such as gas-fired boilers, computer equipment, various digital devices etc. Taking into account high price of such devices its protection is very important.
- Voltage drop
- Impulse noise
- Poor network installation
- Unbalanced load of power transmission line
- Power transmission line break
- Voltage disconnection
Voltage regulators help to escape negative consequences of all these power quality problems
RUCELF voltage regulators definition
S — voltage regulator
D — electromechanical
R — relay
W — wall-mounted
V — floor vertical
F — floor
How to choose voltage regulator?
1. To define mains type
Voltage regulators with connection to household electricity mains 220V for single phase.
Voltage regulators for devices with connection 380V for three-phase.
2. To define voltage regulator type
I. Electromechanical or relay
II. Floor or wall-mounted
3. To calculate consumed power with a store
This information as a rule can be found in any electrotechnical devices manual. Please pay attention to active and reactive load. Reactive load applied to the devices with electric engine consumes from 3 to 5 times more power. Please keep in mind that it is necessary to take into account power consumers simultaneously connected to mains.
