Three Pillars of power cottage

Zoe Dydynskaya Comfortable accommodation in a country house is unthinkable without electrical appliances. And the issue of reliable power is becoming one of the most important for the homeowner. Try to understand how to correctly make a grid cottage. According to experts, it has rested on three pillars: AC voltage stabilizer, UPS and battery power. And it should be set in that order. Centralized power supply voltage, unfortunately, have a number of problems including: invalid deviation of voltage and frequency, high frequency and impulsive noise, the failures and the total disappearance of stress. This leads to the malfunction of electrical equipment, up to its failure. Voltage deviation in most cases can be eliminated by using voltage alternating current. The use of stabilizers enables stable operation and extend the life of electrical equipment, minimizing the likelihood of failure because of poor power supply. Choosing a model of the stabilizer depends on many criteria: power consumption and operating voltage range of power equipment, the presence in its composition motors with high inrush currents, climate, etc. to choose the model of the stabilizer is difficult, so try to help you with this. Advisable to consider the characteristics of a voltage stabilizer in the following order: the number of phases, power output, the operating range of input voltages, the static accuracy of stabilization, speed, operating conditions, weight and dimensions. First we need to understand what problems are common to your mains: constantly over or under voltage surges or dips stress or something else. Next you should decide what model of voltage regulator - single phase or three phase - to choose to operate your equipment and machinery. If among them there is at least one appliance with a three-phase wiring, you must select a three-phase model of the stabilizer. Also, if the total power load is high, and it can be divided into parts, it is best to choose a three-phase model and connecting to distribute the load over the phases. Uniform load distribution will avoid the "phase mismatch, as well as extend the life of the stabilizer. Note that the load on any of the phases does not exceed the allowable values ??for this model the voltage regulator. To construct an integrated power supply circuits country house does not necessarily select only single-phase or just a phase stabilizer. In some cases the power system can be constructed from multiple, different in power and precision stabilization models stabilizers. To choose the model of the stabilizer on the criterion of necessary capacity, it is necessary to calculate the total power consumed by the load. Power consumption of a specific device, you can learn or examining supporting documents, either by looking at the back of the device. When counting should be considered full capacity, as well as inrush current devices. The fact that any electric motor at the moment when energy consumption is several times higher than in normal mode. Value for value current consumption at start-up (enable) the device to the current value in the steady state is called the multiplicity of the inrush current. This value depends on the type and design of the motor, the presence or absence of the soft launch, and can be set from 3 to 7. In the case of the load includes an electric motor, which is the main consumer device (eg, refrigerator), but the inrush current is unknown, the nameplate power consumption of the engine must be multiplied by at least 3, to avoid overloading the voltage regulator at power devices. We recommend you choose the model voltage regulator with a 20-percent margin of power consumption load. First, you will provide gentle operation of the stabilizer, thereby increasing its service life, and secondly, create a reserve capacity for connecting new equipment. With regard to the accuracy of stabilization, to select it is necessary to determine the range of voltages allowed for a protected food stabilizer apparatus. To do this, refer to the instruction manual or the service center of its manufacturer. It is impossible to say exactly what power is necessary for the safe operation of specific equipment, but most of the appliances and equipment "eats" power under 220 V ± 5-7%. BlogThis!
