The purpose of the shorting bar in a current transformer (CT) is primarily to provide a safe working condition when servicing. When maintenance or repairs are required, the shorting bar effectively bypasses the secondary winding of the CT, allowing the current to flow safely through the bar instead. This prevents the generation of high voltages in the secondary circuit, which could be dangerous for technicians working on the equipment. By ensuring that no dangerous voltage is present, the shorting bar allows for safe handling and maintenance of the CT without posing a risk of electrical shock or damage to the equipment.
