Modern practice for LV/MV substation and power
It is advisable to place the substation in a distinct utility building, and it might be positioned next to the generator room, if one exists. Avoid locating the substation in the basement whenever feasible. If a building has only one

6 FAQs about [Underground generator room exhaust shaft]
Who designs and installs a generator exhaust system?
The proper design and functionality of a generator exhaust system falls on the responsibility of the engineering firm of record. If a field fabricated system is being utilized, the design and installation of the system must be a collaboration between the engineering firm and the installing contractor.
What is a generator room?
Generator Rooms With Exhaust Venting Generator Rooms With Exhaust Venting Generator rooms are available with any bunker. A generator room offers sound protection from noisy generators, as well as it allows the generator to be properly ventilated from the rest of your bunker.
Why do generator exhaust systems need to be properly designed?
Generator exhaust systems need to be properly designed to ensure correct engine performance and safe operation. System design has become more complex with the desire to keep emissions low, along with the desire to utilize the heat energy in the exhaust gas.
Where should exhaust air be sourced for a generator?
For generators with remote radiators, it is recommended that the exhaust air should be sourced as high as possible and directly above the generator sets. Significant bypass of ventilation airflow directly into the discharge airflow will lead to reduction in cooling effectiveness and elevated temperatures within the room.
Does field fabricated generator exhaust need insulation?
Field-fabricated generator exhaust also requires insulation. The amount and type of insulation should be stipulated by the mechanical engineer who is responsible for this system to ensure protection for the facility and personnel. Specific design and engineering required to ensure a safe reliable system.
What temperature does a generator exhaust system emit?
Generator exhaust systems must also be engineered and properly installed to accommodate thermal expansion. Generator exhaust systems emit exhaust at temperatures anywhere from 500°F up to 1300°F depending on the unit size, manufacturer, and type of fuel burned.
