About Automatic voltage regulator systems

In order to control the generator output (for example, in ships, power plants, oil rigs or emergency power supply system), the automatic voltage stabilizer. Automatic voltage regulator systems are active, their action on the same principle and the general regulator, but the system is more complex. Automatic voltage regulator includes diodes, capacitors, resistors and potentiometers, and even includes a microcontroller, all placed on a circuit board. Usually installed near the generator, connect some lines with measurement and adjustment of the output of the generator. A step voltage stabilizer is designed to automatically maintain a constant voltage level. step voltage regulators may be a simple "feed-forward" design or may include negative feedback control loops. It may use an electromechanical mechanism, or electronic components. Depending on the design , it may be used to regulate one or more AC or DC voltages.

Single-phase distribution transformer installation site selection

Installation: single-phase distribution transformers can be single pole hanging installation way, poles selection 12 m or 15 m heavy cement pole cement pole.
Installation site selection: After investigation, we found that a single phase step voltage regulators site by fewer geographical constraints, load factors more nature. normally:
When the power supply of three-phase distribution transformers radius is too large, resulting in the low end of the supply voltage, and influence the normal use of electricity, at the end of the installation of power and distribution transformer manufacturer, cutting low voltage network, shortening the low voltage power supply radius, to resolve user voltage bias low problem;
When the overload when the three-phase distribution transformers, according to the load characteristics, select the appropriate branch of single-phase distribution transformers installed, cutting the transfer of load, capacity increase to resolve the issue;
