Step Voltage Regulator(SVR)

Handles voltage fluctuations in 22kV distribution systems!
Contributes to stable voltage regulation!

Feature

Feature

Overseas, the quality of the power supply is not as strictly controlled as in Japan, and the voltage received may fluctuate due to load changes in the surrounding factories. If the voltage fluctuation is large, it can cause problems such as unstable operation of machine tools, malfunction of control equipment, inaccuracy of testing and inspection equipment, flickering and short life of fluorescent lamps, and so on.

This SVR is a large-capacity voltage regulator for the fluctuating receiving voltages that are common in emerging countries. Designed for use overseas, the SVR is available in a range of rated voltages from 22 kV to 6.6 kV. The voltage compensation is up to about 20%, and the capacity can be up to about 8000 kVA in one unit.

  • The transformer part is single winding construction, so it is lightweight and compact.
  • Customization of specifications, such as voltage adjustment range, is possible according to the customer's power receiving conditions.
  • No control power supply is required because the SVR has a built-in tertiary winding.
  • Vacuum valve system is used for the tap changer under load, which eliminates fouling of the insulating oil and significantly reduces maintenance costs.
  • Very stable product with more than 400 units delivered annually to Japanese electric power companies.
