OLTC stands for On-Load Tap Changer.
• An OLTC distribution transformer is a type of transformer equipped with a tap-changing mechanism that allows adjustment of the output voltage while the transformer is energized and supplying load.
• This makes them different from off-load tap changers, which require the transformer to be de-energized before changing taps.

⚙️ Construction & Working

• Tap changer mechanism: Connected to the transformer winding, usually on the high-voltage side.
• Selector switch + diverter switch: Ensures smooth transition between taps without interrupting supply.
• Oil insulation: In oil-cooled transformers, the OLTC is immersed in insulating oil for cooling and arc suppression.
• Automatic or manual control: OLTC can be operated manually or automatically via voltage regulators.
