This Code of Practice provides the details of the general principles to be applied to the design of distribution substations, including substations located at ground floor, basement, upper floor level including at high level in high rise building and outdoor areas.
primary unit substation is a close-coupled assembly consisting of enclosed primary high-voltage equipment, three-phase power transformer and enclosed secondary medium-voltage equipment. The following electrical ratings are typical: Primary unit substations are used to step down utility distribution voltages to in-plant distribution voltages.
Now, let's do some math and size a flooded cell, lead-acid battery for a substation. The battery will be rated 125V DC nominal and have an amp-hour capacity rated for an 8-hour rate of discharge. In most substations, the 8-hour rate of discharge is the standard.
The battery room in a substation is where the batteries are stored. The room is typically located near the substation control room. The room should be large enough to accommodate all of the batteries and have enough space for maintenance work to be performed. The room should also have good ventilation to protect the batteries from overheating.
3.3m above ground for substation without transformer. 3.6m above ground for substation with transformer and 630mm diameter exhaust fan. 3.8m above ground for substation with transformer and 800mm diameter exhaust fan. The recommended maximum ceiling height is 4m but subjected to the required clearance of lifting hoist on the ceiling if provided.
11.3.1 The substation ground level shall be 150mm above the outside ground (pavement) level. 11.3.2 Anti climbing guard shall be provided at the top of the fencing, for example, outriggers made up of 4 strands of barbed wire.
Batteries are to be accommodated in a cabinet within the substation control room - separate battery rooms are not required. Cells are to be mounted in accordance with the manufacturer's recommendations regarding separation between cells to allow air-flow for cooling and for easier access for removal if necessary.

O''Brien of Nolan Battery Company This procedure supplements existing industry standards and is intended to provide the user with the minimum recommended acceptance/capacitytestprocedures for substation switchgear battery systems.
The maximum usable capacity that the battery can release as a backup power supply is the most important indicator. It can be seen from the definition of the state of health (SOH) of the battery that under certain discharge conditions, its value is the ratio [] of the capacity released by the battery from the full state at a certain rate to the cut-off voltage and its
