Overview
Humphrey Substation is an operational electrical substation in the United States, owned and operated by National Grid. It handles voltages of 13800 and 4160 volts.
Humphrey Substation is an operational electrical substation located in the United States, owned and operated by National Grid. As a substation, it plays a critical role in the electrical infrastructure by stepping down transmission voltages for local distribution. The substation operates at voltage levels of 13.8 kV and 4.16 kV, typical for distribution-level facilities. In the United States, such substations are regulated under NERC reliability standards and FERC oversight for grid stability. National Grid, the owner and operator, is a major utility serving the Northeast, ensuring compliance with these frameworks. This facility contributes to grid reliability by managing voltage transformation and power distribution in its service area. Its operational status indicates active participation in the regional electrical network, supporting residential, commercial, and industrial customers.
Environmental context
The substation's location in a temperate coastal region may influence its design for weather resilience, including protection against storms and salt spray. Urban or suburban surroundings would require careful land use integration and electromagnetic field management. Typical substations in this region incorporate modern switchgear and automation for efficiency.
