Description:FIELD OF THE INVENTION
This invention relates to the field of transformers. More particularly, the present invention related to a high-tension Line Voltage Regulator Transformer system increasing that automatically regulates the voltage of high-tension distribution powerlines in remote locations at a very low cost.
BACKGROUND OF THE INVENTION
Most of the 11 KV distribution lines in the Company service area are extended over long distances to feed loads scattered over large rural areas. Poor Voltage regulation / Low voltages have been a common problem for years. Consumers who are connected at remote locations of the network are receiving about 40% lower voltage than the standard supply voltage. Actually measured 1 phase voltage is found below 150 volts. As a standard practice, the length of the 11 lines is generally kept up to 20 Km because beyond this the voltage will drop below 10% limit which causes inefficient operation of electrical equipment/appliances. In the distribution network, we have so many 11KV lines spread over 80 Km which is the main reason behind low voltage in remote areas. Generally, a new 33/11 KV Substation is built in the areas where it is not possible to provide electricity using existing 11KV lines because it is already too long and the voltages have dropped below the acceptable limits. But the problem is that there are not enough loads in the rural areas & it is not possible to justify the cost of constructing an expensive 33/11KV substation. Even a small 33/11KV substation may cost about a million. In the rural areas, we have small load pockets that are spread over a large area.
The existing system lacks innovation as the existing inventions are not able to overcome the problem associated with voltage regulation in remote locations in a cost-effective manner. Thus there is a need for the present invention to overcome the above mention problems.
OBJECTIVE OF THE INVENTION
The main objective of the present invention is to develop a low-cost transformer to regulate the voltage in high-tension distribution lines.
Another objective of the present invention is to develop a transformer with a single winding to be used in high-tension distribution lines.
Yet another objective of the present invention is to develop a transformer having a low impedance.
Yet another objective of the present invention is to regulate the voltage most economically in high-tension distribution lines in remote locations.
Yet another objective of the present invention is to develop a transformer that helps to propagate faults in the high-tension distribution lines to distant substations.
Yet another objective of the present invention is to automatically detect the drop in voltage and automatically boost the voltage by 30% to 40 %. in the high-tension distribution line during transmission to a distant location.
Further objectives, advantages, and features of the present invention will become apparent from the detailed description provided hereinbelow, in which various embodiments of the disclosed invention are illustrated by way of example

the OLTC device(134) detects the changes of the high-tension distribution line voltage automatically;
the OLTC device(134) commands the tap changer unit(132) to change the tap accordingly to bring the voltage of the high-tension distribution line to the desired voltage;
thus regulating the voltage in the high-tension distribution line automatically;
characterized in that, the High-tension Line Voltage Regulator Transformer system(100) is a single winding transformer that is installed in the high-tension distribution line and thus able to regulate the voltage of the high-tension distribution line;
characterized in that, the High-tension Line Voltage Regulator Transformer system(100) has low impendence because of the single winding(118) thus the High-tension Line Voltage Regulator Transformer system(100) improves the voltage in the high-tension distribution line on a remote location that is located far from the substation;
characterized in that, the High-tension Line Voltage Regulator Transformer system(100) has low impendence because of the single winding(118) thus the High-tension Line Voltage Regulator Transformer system(100) helps in transferring the downstream fault currents to the source side so that the protection relay at the substation can pick up the remote end fault with the same level of sensitivity;
characterized in that, the High-tension Line Voltage Regulator Transformer system(100) has low impendence because of the single winding(118) thus the High-tension Line Voltage Regulator Transformer system(100) has low cost as compared to the conventional high-tension transformer.
