Advantages Of Voltage Adjustment With On-load Tap Changer

The voltage adjustment of the high-voltage/medium voltage and load regulating transformer can keep the supply voltage of the lower-level medium voltage and low-voltage power grid within the allowable range of the slow voltage variation. Digital voltage regulator In this side of the application can also achieve other specialized functions (such as line pressure drop compensation, power grid parallel operation, transformer parallel operation, etc.).

In determining the expected voltage position, consideration must be given to the power grid structure, the type and specification of the network elements, the size of the power supply range and the load conditions of the grid, and, if necessary, the small power plants of the low-voltage and medium voltage grids.

Setting the expected voltage value is directly related to the defined voltage range, the voltage condition of the power grid, the influence on the power consumption of the power equipment and the transmission loss of the power grid. Therefore, the use of on-load tap changer for voltage adjustment allows the power grid voltage and power conditions to achieve optimal.

The use of on-load tap changer can reduce the cost of reactive power compensation devices and save energy. The use of on-load tap changers in voltage adjustments is a standard solution for both public and industrial power supply.
