A generator transformer steps up the voltage from the generator (usually 11–33 kV) to higher transmission levels (up to 132 kV or more) for efficient power delivery to the grid. It acts as a crucial link between the power plant and the transmission network.
The delta-star configuration minimizes circulating currents and provides a neutral point for grounding and protection. It also helps isolate the generator from potential harmonics and unbalanced loads in the grid.
An On-Load Tap Changer (OLTC) allows voltage adjustment under load conditions, maintaining stable voltage output despite fluctuations in generation or grid load—crucial for power plant operations.
