On Load Tap Changer in Transformers: Working Principle Explained

Introduction to Voltage Regulation in Transformers

Having a constant voltage level is critical in ensuring the efficient running of electrical power systems. The conditions in the power transmission and distribution systems are dynamic, leading to changes in the voltage level. To tackle this change without affecting the power flow, a transformer has sophisticated voltage control systems. Circuit breakers in the transformer are a crucial part of these systems, enabling an On Load Tap Changer in Transformers in place. This makes the circuit breaker indispensable in the modern power sector, which focuses on having a constant power supply.

On Load Tap Changer In Transformers

On Load Tap Changer in a transformer is a mechanical system, which allows the voltage ratio in the Transformer to be changed when the Transformer is under load. In this technology, the Transformer is not de-energized because the tap change in the Transformer occurs when the Transformer is in its normal operational mode. On-load switch in a Transformer changes the number of turns in the Transformer.
