Power engineering services are known for the infrastructure they
supply for everyday electricity needs. But, in addition to basic power
supply, many power engineers also specialize in emergency power
infrastructure, from portable disaster generators to large-scale
industrial generators used by businesses and organizations worldwide.
If your area suffers a natural disaster that cuts off commercial electricity, portable generators could be your source for heating, cooling, and even running water, while industrial generators are the ones that keep hospitals, data centers, and police departments running during commercial electricity outages. Far from merely keeping the lights on until commercial energy supply returns, emergency power is also about preventing catastrophes and saving lives.
How Do the Emergency Generators Supplied by Power Engineering Services Work?
There are several differences-and also some similarities-between industrial and residential generators. To start with the similarities, both run on petroleum fuels and allow buildings to switch from commercial energy to generator energy in the event the former becomes unavailable. But how they accomplish the switchover and the length of supply they offer is what sets them apart, as well as that industrial models usually run on diesel fuel or natural gas, while home models usually run on either diesel fuel or gasoline.
The switchover from commercial to generator supply is accomplished by switchgear, a combination of fuses, circuit breakers, and/or electrical disconnects that isolate electrical equipment within a power system, with electrical disconnects and circuit breakers being the most common switchgear for emergency back up generators. Most generators operate using one of two electrical disconnect scenarios: break before make, in which a building de-accesses commercial supply before accessing generator supply; and make before break, in which a building accesses generator supply before de-accessing commercial supply.
As one might expect, make before break is ideal for businesses and organizations that require uninterrupted supply to maintain critical functions, such as hospitals, data centers, defense organizations, and laboratories, while break before make is ideal for entities that can briefly lose their energy source before accessing their generator. If given the choice, entities often opt for break before make, because it cuts down on generator caused by false interruption signals in the commercial energy supply.
How long a generator's energy lasts depends in part on its volume of fuel storage, but it ultimately depends on the size of the facility it powers. In most cases, a single, large-scale industrial generator can support an average sized hospital for 8 hours, with some hospitals having enough generators to supply energy for as long as 3 days in the event of a long outages. In the event of even longer outages, additional fuel or portable generators may be mobilized to provide support when onsite generators have expended their fuel.
