Basic Requirements for a SubstationA substation is a critical facility in the power system, responsible for converting transmission voltages to levels suitable for distribution or further transmission. It not only performs voltage transformation but also handles the protection, control, and monitoring of the power system. To ensure the safety, reliability, and efficient operation of a substation, a series of fundamental requirements must be met. Below are the main requirements for the design and

A modular substation is a solution where the main components of a substation are pre-manufactured, assembled, and tested in a factory before being transported to the site for rapid installation. This design approach offers several significant advantages over traditional substations, as detailed below:1. Shortened Construction Time Prefabrication and Pre-assembly: The various components of a modular substation are manufactured and assembled in a controlled factory environment, reducing on-site co
