Technology Introduction
To address and resolve numerous issues associated with manual transformers, a linear On-Load Tap Changer (OLTC) technology has been developed, enabling real-time voltage adjustment under load. This technology has been applied to create intelligent transformers, smart transformers, smart voltage regulators, and transformers for distributed power systems (solar, wind power).
On-Load Tap Changer (OLTC) technology, capable of real-time voltage adjustment at high voltage, is a critical core technology in the power industry. While OLTCs are typically installed in power transformers for substations, voltage instability issues often persist due to technical limitations. Furthermore, most transformers other than those in substations are passive, meaning voltage cannot be adjusted under load. If voltage adjustment is unavoidable with manual transformers, it requires a power outage, which is a significant problem as frequent outages are impractical after installation.
To overcome these limitations, a linear OLTC (On Load Tap Changer) has been developed that allows real-time voltage adjustment in any scenario. Conventional advanced technologies primarily use rotary rotation methods, but this developed technology employs a completely different linear sliding method. This patented technology has overcome the technical limitations of previous advanced technologies.
OLTC technology for stabilizing transmission/distribution voltage is a vital core technology in the power industry. It is primarily used in substations by attaching an OLTC to a power transformer and is applied to line voltage regulators and systems. Since manual transformers are used, there is a serious problem that voltage cannot be adjusted. To improve this, a linear sliding type OLTC (On Load Tap Changer) has been developed. While existing overseas technologies are all rotary, this technology is a patented linear sliding method, completely different from existing approaches.
Thanks to this developed technology, OLTC intelligent transformers and smart transformers can be utilized, leading to voltage stabilization, improved efficiency, reduced power bills, and decreased losses. Electricity is supplied from power plants through substations to consumers (factories, buildings). When transmitted over long distances via wires, losses occur due to wire resistance, causing voltage drops and increased instability due to load fluctuations. Conventional passive transformers cannot respond to unstable voltage.
When unstable voltage is applied to a passive transformer, the output voltage becomes unstable, forcing all loads to operate in an unstable state, thereby reducing efficiency and increasing losses. Unstable voltage, whether low or high, leads to decreased efficiency and increased losses. A 5% voltage drop can increase losses by 9.75%, as current rises and losses are proportional to the square of the increased current. Using an "intelligent transformer" capable of "real-time voltage adjustment" stabilizes the voltage, improving efficiency, reducing losses, and lowering power bills. While conventional electrical devices have single unique functions, the developed "intelligent transformer" and "smart transformer" technologies make multiple functions possible.
