Inside building there are three major services which are electrical service, mechanical service, and fire suppression system. Today lets have a look at electrical services.
The security of a building’s electrical service relies on the service provider and facility location. For example, in an urban environment, the system may be arranged as a network with services to a building consisting of multiple underground feeders, multiple transformers, and may have redundancy built into the integrity and reliability of the service. Alternatively, in a suburban or rural environment, may be transported by overhead transmission lines, asters and more accessible for human intervention.
Emergency generators supply power to critical building obtain operations during utility power loss. Critical life safety systems include fire pumps, elevators and smoke management systems, emergency egress lighting, and fire aspects of these systems, especially when occupants are forced to evacuate a building, emergency generators must respond when called upon to operate. System responsiveness depends on availability, design, use of appropriate technology, maintenance, and the presence of knowledgeable facility staff who are familiar with operating sophisticated building technology and systems.
Redundant emergency power systems increase the likelihood that systems will be available when called upon.
Ideally, redundant systems should be located remote from each other.
Many building codes mandate periodic testing of emergency generator systems, to ensure systems remain in working order at all times. Testing also familiarizes building operating personnel with system operations and better prepares them to react quickly and correctly under the pressures of an emergency situation.
