It is not a secret for anybody that the state of communal services of cities and adjacent villages in our country is, to put it mildly, far from that which can provide honest taxpayers with a peaceful and prosperous existence. So, for example, urban electrical networks and the transformer industry that feed them do not absolutely guarantee today their consumers reliable and energy supply that meets international standards and regulations.
The situation is even worse with electricity supplied to villages and suburban settlements. Due to the lack of the necessary funds and specialists, there is practically no work on the timely maintenance of cable and overhead lines, transformers and protective disconnecting devices. They don’t even speak in a whisper about allocating money for scheduled and capital repairs.
Overloaded transformers and incorrectly calculated cable lines, aged insulation of electrical wiring and wires suitable for homes contribute to the occurrence of significant voltage drops and lead to a rapid failure of household appliances and lighting equipment. Bear in mind, however, that the existing legal framework is not on the consumer side today, and all the costs of repairing burnt equipment will fall entirely on your shoulders.
Often, specialists who arrive in the corners of our country forgotten by God, only aggravate the already difficult situation when they switch the supply transformers to additional windings that increase the output voltage. As a result, slightly raising the voltage in the network in the evening, they thus create a very dangerous situation in the unloaded daytime period of time. The voltage entering the house sometimes reaches 247; 260; 270 V and ruthlessly "kills" all household electrical appliances included in the home network and you will have to contact the service centers for the repair of refrigerators and not only.
Gloomy, you say? No, there is a way! Through the efforts of our and foreign experts, we managed to find a way out of this situation. Created a unique device - a household voltage regulator. The device, which is a modern electronic system, makes it possible in a fraction of seconds to equalize the drops and surges of the mains voltage, to provide consumers with high-quality alternating voltage within the value of 220 V ± 5%.
Electronic voltage regulators will provide reliable protection for your household electrical equipment and any household appliances. Their work is noiseless, but painstaking. The design of the electronic stabilizer ensures its reliable operation in any operating conditions for many years without requiring any maintenance.
How to choose a voltage regulator To choose the right voltage regulator, it is very important to determine the parameters of your electrical network and the electrical power consumed during the day. Incorrect source data will not allow you to choose a voltage regulator that meets your requirements, which provides the optimum mode of its operation. As a result, you throw money away without achieving the required results.
1. The number of phases of the supply network Manufacturers produce voltage regulators for both single-phase and three-phase electrical networks . For apartment owners of multi-storey buildings, traditionally powered from household electric meters located on the landing, a single-phase electronic stabilizer is quite suitable. Happy owners of private housing, country cottages or country houses for the most part use three-phase networks. When choosing a voltage regulator, they should pay attention to the three-phase models. In fairness, it is worth noting that such a source of stabilized alternating voltage is no different in its parameters and constructively consists of three single-phase units connected in a “star”.
2. The value of the lower and upper values of the input voltage When choosing an AC voltage regulator, it is very important to know the range of voltage values in your power supply. For this purpose it is necessary to make a map of measurements of the mains voltage during the day. In this case, it is not necessary to ask for leave from work so that, sitting near an electrical outlet, every half hour to take readings of a control voltmeter. It will be sufficient to connect the test leads of the measuring device to the home power grid and record the values obtained in the evening after work and in the morning before going to work.
3. Rated power of an AC voltage regulator A very important parameter of any voltage regulator is its full rated power. It actually determines the efficiency of the device when connecting a particular load. Therefore, to select an AC voltage regulator, knowledge of the power consumption at the lowest voltage value in your network is of the greatest importance. At the same time, having even school knowledge in electrical engineering, you can easily calculate this value. Add up the power rating of all household appliances that work in the evening, and you will get the same value of power consumption at the lowest voltage in your home network.
