The voltage in a distribution line is not constant. It may be 1.05 p.u. at generator terminal and 0.95 at the load side. Depending on the place the transformer is used, we may need to adjust the transformer ratio to get similar load voltage.

    On-load voltage transformer is widely used in power network for its excellent property. Visit www.zjyb-electric.com for more high voltage pulse transformer information. Transformer Standard of SZ11 Type 35kv Series On-Load Regulator Transformer: GB1094.1~2-1996 power transformer GB1094.3,5-2003 power transformer PDF Download. Yuebian transformer through a feeder impedance of 38.2 + j140 Ω. The transformer’s equivalent series impedance referred to its low-voltage side is 0.12 + j0.5 Ω. The load on the transformer is 90 kW at 0.85 PF lagging and 2300 V. (a) What is the voltage at the power source of the system? (b) What is the voltage regulation of the transformer?

    Mar 14, 2019 · What is Voltage Regulation? Voltage regulation is a measure of change in the voltage magnitude between the sending and receiving end of a component. It is commonly used in power engineering to describe the percentage voltage difference between no load and full load voltages distribution lines, transmission lines, and transformers. Explanation of Voltage Regulation of … A simple voltage regulator can be made from a resistor in series with a diode (or series of diodes). Due to the logarithmic shape of diode V-I curves, the voltage across the diode changes only slightly due to changes in current drawn or changes in the input. When precise voltage control and efficiency are not important, this design may work fine.

    The Voltage Transformer can be thought of as an electrical component rather than an electronic component. A transformer basically is very simple static (or stationary) electro-magnetic passive electrical device that works on the principle of Faraday’s law of induction by converting electrical energy from one value to another. Utilities have voltage regulation equipment at various points of the distribution system to insure customers receive the proper voltage at their meter during any load level. The past and even present voltage regulation philosophy was not developed with widespread Distributed Energy Resources in mind at customer premises.
