The impact that a power outage has on our lives is critically increased due to the sole fact that we are so reliant on electricity. Homes, health care facilities, industry, and business all rely on electrical power not just for comfort, but to operate safety systems and protect property.
Key to a ::standbygenerator system:: is its capacity to discover a power outage and then start and run automatically without human intervention. In conjunction with an automatic transfer switch, they are permanently installed systems that discover a power outage and then provide the home or facility with power until the electric utility is capable to restore service. The generator will also automatically shut down once utility power is restored.
Critical Environments
Critical environments are those that cannot tolerate a power interruption. These include hospital operating rooms and intensive care units, computer installations, and other critical systems. These systems utilize uninterrupted power to prevent their systems from experiencing an outage, even for a few seconds.
Electrical power is stored in batteries. An inverter switches the battery power to the same power provided by the utility, which then powers the equipment connected to it. If power is interrupted, the batteries continue to supply power until the standby generator comes online and takes over keeping the batteries charged until the utility restores power .
In hospitals, other systems may not call for uninterrupted power, but they cannot be out of service for any length of time. During an outage, standby generators are the ones keeping these systems operational.
Commercial Facilities
Large commercial buildings have safety systems that rely on electrical power. Everything from emergency lighting to ventilation and fire safety systems require electricity, and when the power goes out, standby generators fill in until the electric company turns the power back on. During long-term outages, the batteries in emergency lights may have only a few hours of useful life . Without a standby generator to take over when the power goes out, emergency lights will fade and building occupants won’t be able to find their way.
