Off Load Tap Changer

Off Load Tap Changer (OCTC) is a device used in transformers to adjust the output voltage by changing tap positions when the transformer is completely de-energized (no load condition). It helps in setting the required voltage level before operation.

• Tap Changing Without Load – Operates only when transformer is switched OFF

• Voltage Adjustment Facility – Multiple tap positions available

• Simple & Reliable Mechanism – Manual operation

• Cost-Effective Solution – Lower cost compared to OLTC

• Robust Construction – Long service life

• Low Maintenance Requirement

• Improves Voltage Regulation – Adjusts output as per requirement

• Suitable for Distribution & Power Transformers

• Safe & Easy Operation – Clear position indication

• High Mechanical Strength
