An off-circuit tap changer is a mechanical device used to adjust the voltage ratio of a transformer by changing the tap connections on the primary winding. Unlike on-load tap changers, off-circuit tap changers operate only when the transformer is de-energized, providing a simple and cost-effective method of voltage adjustment during maintenance or configuration changes.

Engineered for long service life and minimal maintenance, the off-circuit tap changer ensures stable voltage control across various load conditions in distribution and power transformers. It is typically used in applications where voltage adjustments are infrequent and can be performed during scheduled downtime.

Features:

Precise voltage adjustment through manual or motor-operated tap switching
Suitable for oil-immersed power and distribution transformers
High mechanical durability with robust internal contacts
Available in rotary or linear configurations
Built-in locking mechanism to prevent accidental switching
Compact design for easy integration into transformer tanks
Customized tap positions and current ratings as per specification

Applications:

Power and distribution transformers
Substation transformers
Renewable energy transformer systems
Rural electrification and grid regulation
Industrial transformer installations
