Substation 493 - Electrical Substation in the United States

Substation 493 is an operational electrical substation situated in the United States, with geographic coordinates 38.100711, -122.270169. As a substation, it is a key node in the electrical infrastructure, facilitating voltage transformation and power distribution. The facility is part of the broader U.S. power grid, which is regulated by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC) for reliability and market oversight. Substations of this type typically operate at transmission or sub-transmission voltages, ranging from 69 kV to 765 kV. The facility's location in the United States places it under NERC reliability standards, which mandate compliance with grid stability and security requirements. The substation likely includes switchgear, transformers, and protection systems that adhere to standards like IEEE C37 for high-voltage equipment. The environmental context of Substation 493 is influenced by its location in a region with moderate seismic activity and a Mediterranean climate. The facility's design and maintenance must account for these conditions to ensure grid reliability. As part of the electrical infrastructure, it supports local communities and industries by providing stable power supply, contributing to the overall resilience of the U.S. power system.

The substation is located in a region with a Mediterranean climate, characterized by dry summers and wet winters, which can affect equipment insulation and cooling. The area is also subject to seismic activity, requiring substation structures and equipment to be designed for earthquake resilience. The facility's urban or rural setting influences its environmental impact, with potential considerations for electromagnetic fields and land use.
