What is the function of a transformer in a substation?

• A. To generate electrical power
• B. To step up or step down voltage levels in the electrical system
• C. To monitor electrical load
• D. To store electrical energy

Answer: (B)

The function of a transformer in a substation is primarily to step up or step down voltage levels in the electrical system. This process is essential for efficient electricity transmission and distribution. When electricity is generated, it is typically produced at a relatively low voltage. To transmit this electricity over long distances, the voltage needs to be increased to reduce losses due to resistance in the conductors. This is accomplished by a step-up transformer. Conversely, when the electricity reaches its destination or a distribution area, the voltage must be stepped down to a safer and more usable level for end-users, such as homes and businesses. This is done using step-down transformers. By changing the voltage levels, transformers ensure that electrical energy can be transmitted efficiently and safely across the power grid. In addition, transformers play a crucial role in maintaining the balance and stability of the electrical system. They help in managing voltage levels to prevent overloads and improve overall system performance. While monitoring electrical load and storing energy are important tasks in power management, those functions are typically handled by other devices or systems in the substation, not the transformer itself. Similarly, transformers do not generate electrical power; they only alter voltage levels of the current that is being transmitted.
