Answer: A substation's primary role is to act as a hub for electrical power, directing and conditioning it for safe and efficient transmission and distribution. The transformer is a vital part of this system. For example, in a step-up substation, a transformer increases the voltage from a power plant so that it can be transmitted over long distances with minimal loss. In a step-down substation, another transformer reduces this high voltage to a level that can be safely used by industries and homes. Our company provides the specialized tools necessary for the installation, testing, and maintenance of these large power transformers and other key components within the substation.
