RailCorp traction substations and sectioning huts contain equipment (1500V rectifiers and
1500V DCCB’s) that produce significant amounts of heat. The rooms which contain this
equipment are usually not suitable for VRLA (gel) batteries as RailCorp locations are
naturally ventilated and the resultant high ambient temperature causes significant
reduction in life and reliability of the battery.
A dedicated battery room is one way of creating a suitable environment for VRLA (gel)
batteries.
The other requirements for a battery room depend on the following:
– fire and life safety requirements
– network criticality
– a requirement as determined from a specific risk analysis
