Technology Introduction
To improve and solve many problems of manual transformers, a linear OLTC (On Load Tap Changer) technology has been developed that can adjust the voltage in real time under load. By applying this, intelligent transformers, smart transformers, smart voltage regulators, and distributed power (solar, wind power) transformers were developed. On-Load Tap Changer (OLTC) technology, which is capable of real-time voltage adjustment at high voltage, is a very important core technology in the power industry. The OLTC is installed in a power transformer and is mainly used for substations, but the problem of voltage instability still persists due to technical limitations. In addition, all other transformers except power transformers installed in substations are passive transformers, and voltage cannot be adjusted at all under load. Still, if the voltage is unavoidable, the tap of the manual transformer must be adjusted after a power outage, but there is a serious problem in that the voltage cannot be adjusted at all after the transformer is installed, since power outages cannot be frequently performed. To improve this problem, a linear OLTC (On Load Tap Changer) was developed that can adjust voltage in real time under load. This enables real-time voltage adjustment in any case. Conventional advanced technologies are all rotary rotation methods, but this developed technology is a technology that has been developed with a completely different linear sliding method and is a patented technology. On-load tap changer (OLTC) technology for stabilizing transmission/distribution voltage is a very important core technology in the power industry. It is mainly used for substations by attaching an on-load tap-changer OLTC to a power transformer, and it is applied to a line voltage regulator and system. Since the transformer is used manually, there is a serious problem that the voltage cannot be adjusted. To improve this problem, a linear sliding type OLTC (On Load Tap Changer) was developed. While all of the existing overseas technologies are rotary, this technology is a patented technology with a linear sliding method that is completely different from the existing method. Due to this developed technology, OLTC intelligent transformer and smart transformer can be used, resulting in voltage stabilization and efficiency improvement, reducing power bills and reducing losses. Electricity is supplied from the power plant through the substation to power consumers (factory, building). When supplying such a long distance through a wire, a loss occurs due to the resistance of the wire, the voltage drops due to the loss, and becomes more unstable due to the influence of the load. When unstable voltage is applied to the transformer, the conventional passive transformer cannot respond at all. When unstable voltage is applied to a passive transformer, the output voltage must be unstable, and all loads must be used in an unstable state, reducing efficiency and increasing losses. If the voltage is unstable, the efficiency decreases and losses increase even when the voltage is low, and a higher voltage becomes a bigger problem. It's like high blood pressure and low blood pressure frequently repeating, and it's like a car repeating speeding and slowing from time to time. When the voltage is used as a “stable rated voltage”, the loss is least and the efficiency is good. When the voltage drops by 5%, the losses increase to 9.75%. This is because when the voltage drops, the current rises and the loss is proportional to the square of the risen current. In the case of using “intelligent transformer” capable of “real-time voltage adjustment”, the voltage is stabilized, improving efficiency, reducing losses, and reducing power bills.
