Tech comes in many forms. While the younger generation think of tech as being smartphones and apps, technology is advancing in all walks of life. If you have every suffered a major power outage, then this sort of tech may interest you – power generators!
An emergency power generator provides electrical power when power cannot be supplied through the national grid. They can be used to provide literally ‘emergency’ power in the event of power cuts, as well as power in locations where mains power isn’t supplied, such as in fields holding events, or in city locations where there is no access to a power supply.
Most power generators are diesel powered and conform to industry standard regulations concerning emissions – see our green policy. The newer the generator, the better it is in this respect but – so long as you use a reputable supplier – your machine should be of an acceptable standard in terms of emissions.
Works Like Charging A Car Battery
The generator usually has a diesel engine that keeps an alternator charged up. The alternator provides current and therefore electricity via cabling to an electrical power socket. This is broadly similar to a car’s charging system where the power from the engine drives the alternator which in turn charges the battery from where power is drawn to power the car’s ignition, lighting and other electrical equipment.
180 Year-old Tech
Generators work by means of electromagnetic induction, which was discovered over 180 years ago by Michael Faraday. Electricity is generated by moving an electrical conductor within a magnetic field. If you have ever used a dynamo torch, you will have experienced this technology first-hand. The most efficient way of creating an electrical current is by rotating a copper coil.
The movement of the electrical conductor results in a voltage difference at each end of the copper coil and this causes an electric current. The same principle is used in power stations – the main difference is the method of moving the conductor to generate power. Power stations use steam power – even nuclear power stations ultimately heat water to power turbines with steam – but this is not practical for small generators, so petrol or diesel is used to power an engine, which is used to power the conductor. In this respect, it really is similar to how a car engine charges the battery – an alternator is simply a dynamo that generates an alternating current.
In the case of a generator that is permanently connected to provide power in the event of emergency power loss, a transfer switch is connected which will switch on the generator once it senses mains power has been cut.
Generators often come with a large fuel tank, but they will generally require refilling if they are needed for an extended period. You may either refuel the tank yourself or use our fuel management service; we will monitor your fuel use and ensure the generators supplied to you are fuelled at all times so as to avoid possible downtime.
What Can They Be Used For?
Generators can be used just about anywhere. Smaller units can provide power to appliances such as in and around a building site, while large outdoor events, temporary exhibitions and music festival sites, would use our larger heavy duty varieties. Certain applications where uninterrupted power is essential, such as medical facilities, would make use of generators that can cut in as and when required.
It’s important to ensure you select the correct specification generator based on known or possible needs. If you know exactly what you’re supplying power for, then your generator supplier can advise on the best solution for your needs.
If it’s for emergency use – for example, you’re hiring one as back up if a power supply should fail or be interrupted – then a careful gauging of likely demands should be made. Again, we can guide you.
A smaller, easily portable generator will be fine for supplying a few appliances and may be all you need – and will be commensurately portable so as to be moved easily around the site or area. On the other hand, you may need a more powerful generator to provide power to a whole property or site in the event of an outage. Portability will be less of an issue of course, but your generator will be a heavier duty model designed to provide more power.
So there you have it, if you have a power cut and cannot afford to lose juice, know that you can get an emergency power generator. You can buy small ones from most hardware shops and even through Amazon, but these are not very efficient and costs will quickly escalate if you need power for more than a few hours. For longer term power needs, you can hire a larger generator, such as one of Templant’s emergency power generators.
