Ground Grid Design- Substation Below Grade Engineering
Ground grids are installed at a depth where the currents flowing in from the above grade steel structures are easily dissipated into the earth. This is accomplished by:
Substation Design
Learn the details that go into designing a substation.
Determining short-circuit rating of circuit breakers
Determining the short-circuit rating of the breaker requires knowledge of the prospective fault current at the panelboard. Following section provides a simple method to obtain this currents magnitude.
