How Gensets Work
Gensets operate on the fundamental principle of electromagnetic induction. At the core of this process is the alternator, propelled into motion by the engine's mechanical force. As the engine drives the alternator, a magnetic field is generated within a wire coil housed within the alternator's core. This magnetic field rotates rapidly, inducing an electrical current within the coil through the phenomenon of electromagnetic induction.
The resulting electrical output takes the form of an alternating current (AC), characterised by its oscillating direction of flow. To render this alternating current usable, voltage regulation mechanisms are employed to stabilise the electrical output to meet desired parameters.
Furthermore, distribution panels are utilised to channel the electricity to various loads, ensuring a reliable and consistent power supply to critical systems and equipment. Through this intricate process, gensets seamlessly transform mechanical energy into electrical power, providing a dependable source of backup electricity during grid outages or in remote locations where grid access is limited.

Let's use a simple analogy to illustrate the difference between gensets and DRUPS systems:
Imagine you are driving a car on a long road trip. Your car represents your power supply, and the fuel tank represents the electricity stored in batteries or capacitors.
Gensets
Gensets are like traditional cars with combustion engines. When you need more fuel (electricity), you stop at a gas station (start up the genset) and fill up your tank. It takes a little time to refuel, but once you are back on the road, you can keep driving without any interruptions until you need to refill again.
DRUPS Systems
DRUPS systems are like hybrid cars with both an engine and a battery. When you are driving a hybrid car and you run out of fuel (experience a power outage), the battery kicks in immediately to keep the car moving seamlessly. You will not even notice the transition because the battery starts working instantly, ensuring a continuous and smooth ride without any interruptions.
In this analogy, the traditional car represents the genset, which requires a short pause to refuel (start up) when it runs out of fuel (experiences a power outage). The hybrid car represents the DRUPS system, which seamlessly switches to battery power when the fuel runs out, ensuring continuous movement without any interruptions.
