AC automatic voltage regulators

Step Voltage Regulators applied in the utility’s distribution systems are generally medium-voltage mechanical automatic voltage regulators (AVR). It should be noted that there are two distinct types of AC automatic voltage booster regulators: Medium-voltage (mechanical) and the Low-voltage regulators (mechanical or electronic). The difference in their operation and design clearly demonstrate that their applications are not the same. The latter is intended to protect end-user devices from overvoltage and undervoltage conditions . Nonetheless, this post will focus on the medium-voltage regulators, which is primarily used by the electric utility to compensate for the voltage drop in the feeders or distribution systems. In addition, the term step-voltage regulator is often used to refer to utility AVR.

Wound Core Distribution Transformer

Wound Core Distribution Transformer
FARADY S11-M.RL, S13-M.RL series of three-dimensional triangular wound core transformer breaking the traditional planar structure, use symmetrical three-phase three-dimensional structure, the product is completely symmetrical three-phase core magnetic circuit reluctance greatly reduced, excitation current and significantly reduce the unload loss,which is a use of traditional materials, but runs quieter, more compact energy-efficient transformers. Its energy saving, environmental protection material on the outstanding performance of the province, and in full compliance with the energy policy.

Farady step voltage stabilizer

Farady auto load booster operate on a closed loop control. The output voltage is measured and compared with a high-stable reference in an electronic control unit. Whenever the output voltage deviates from the reference for more than 1% (standard), the servo drive is switched on until the output voltage has again reached the nominal value. This results in a booster voltage, to be added to or taken away from the line voltage, corresponding to the deviation. This step voltage stabilizer are suitable for supplying resistive, inductive, or capacitive load, neither radio interference nor additional harmonics occur within the permissible operation range.
