A longtime resident of Santa Ana, California, Dianoush Emami is an experienced electrical engineer who served six years at Bechtel Power Corporation. In this role, he designed power system control systems, computer system applications, and control systems. Dianoush Emami has extensive engineering expertise in high voltage transmission and substation design.
High voltage substations are integral to electricity distribution from power stations to many end users. These substations convey electricity in the order of 11,000 or 33,000 volts; the electricity is doled out among customers who use fractional voltage components. High voltage substations are often constructed outdoors on parcels of land that are a moderate distance from nearby occupants to prevent discomfort due to sounds made by elements of the substations, such as transformers.
Low voltage substations are designed to convey a limited voltage of electricity. The standard voltage processed by these substations is below 11,000 volts. They are mostly constructed indoors to prevent exposure to factors that can raise the voltage above the required range because of the restricted levels of voltage required at these substations. The presence of metal contaminants in the air is a factor. Some commercial buildings have low voltage substations.
