General
Ideally the distribution lines should to be able to keep the whole line of constant voltage, but in actual, the impedance of the distribution line will result in that the voltage of end and terminal is not same( Figure 1).
Electric power system: Low voltage will affect the power supply equipment output, reducing supply reliability, but also affect their own economic power, voltage drops particularly severe, even voltage collapse may occur, the frequency of loss and blackouts and other incidents.
Electric equipment: Voltage quality have an impact on safe and economic operation of various types of equipment such as the asynchronous motor, for example, if the voltage decreases, the voltage will reduce torque so that the slip is increased, so that the stator and rotor current significantly increases, resulting in motor temperature liter rise, possibly even burning motor; on the contrary, when the voltage is too high, due to the excitation current and iron loss greatly increased, resulting in motor overheating, efficiency is reduced.
Power system losses: In conveying power certain time, the square of system losses and operating voltage, if the voltage decreases, the current increases and the loss, the loss will become larger system.
Work Principle:
TVR-line voltage regulator is a special design autotransformer with on-load tap changer, it can automatically "monitoring" and smoothly adjusts the output voltage, and also guarantee the output voltage within the voltage requirement. 27 taps regulation can meet every step 0.75% regulation accuracy. See blow figure5
In Figure 6, is an utility sample for a factory which require 400V electric power, but the power line is not stably in the summer because the load is 120% of rated capacity, so the power to the factory is lower than 360V, all the electric equipments in the factory can not use. After install auto voltage regulator, it can adjust the power line voltage from 8038V to 11000V and keep it stable with 2% accuracy, so the power to factory can be keep at 400V(+8V accuracy).
