The Standby Generator Working Principle

standby generator working principle

Having a standby generator in your home can give you peace of mind during a power outage. This means you will be able to keep your house running while you are away, and you will not have to worry about your family’s safety. Having a standby generator is a great way to save money on your power bills.

Over-speed protected

Using over-speed protected standby generators has a number of benefits. For instance, it reduces eddy current losses as the frequency of the system increases. It also prevents the loss of power that could be caused by a turbine over-speeding.

There are many factors that go into a properly designed over-speed protection system. These factors include the number of sensors and circuit breakers involved, the system’s technical capabilities, and the corresponding hardware and software requirements.

The main benefit of an over-speed protected standby generator is its ability to stop a turbine from over-speeding. The system is designed to work with the main governor valve control system to minimize the impact of overspeed. The system will also maintain the turbine’s stability during a partial load loss.

Automatic transfer switch

During a power outage, an automatic transfer switch transfers the electrical energy between the primary and backup power sources. Automatic transfer switches are installed in facilities that require a continuous power supply such as hospitals, aerospace facilities and data centers.

When the primary power source fails, the automatic transfer switch invokes a backup generator. The standby generator will power electrical loads until the primary power is restored. When the utility power comes back on, the automatic switch will switch the load back to the primary power source.

There are three types of automatic transfer switches. A dual power automatic transfer switch transfers between two power sources, while a single power automatic transfer switch transfers power between a generator and a network.

The dual power automatic transfer switch is most often used in elevators and fire fighting. It is controlled by a microprocessor and is used to automatically switch between generator and network power.

Cooling and lubricating system

Various engine and generator systems can be adapted to provide a cooling and lubricating system for a standby generator. For a typical marine engine, the system is typically installed in a tilted position. This is to provide a cooling system that can counteract the heat from the alternator. It also provides a lubrication system that can cushion engine bearings against shocks and rust.

One type of system involves a primary pump that circulates a portion of the cooling-oil lubricant from a primary reservoir. This pump is usually mechanically driven, but electrical switching can also be used.

In the event of a primary pump failure, a second pump will take over the circulation of the cooling-oil lubricant. This second pump will also provide a pressurization function. The pressurization function can be accomplished through the use of a high pressure relief valve.

Power output capacities

Whether you are buying a standby generator for your home or for your business, there are several important factors to consider. You will need to consider your initial costs, your future load levels and your capacity requirements to determine the best generator for your needs. You will also need to be aware of the different generator output capacities and ratings.

Standby generator power output capacities are generally rated in kilowatts (kW). The higher the rated watts, the higher the generator’s capacity to provide power continuously. You can find out more about generator output capacities by visiting the manufacturer’s website.

In addition to watts, generator ratings also include critical parameters like the type of load, the character of service expected, and the number of running hours. The ratings provide enough information to help you make an informed choice.


Purchasing a standby generator is a long-term commitment. Considering the investment’s longevity, you want to be sure you’re getting the best product possible. A standby generator can run the lights, run the refrigerator, power the HVAC, and even power your home security systems. A warranty is also a must. Whether you’re in the market for a new generator or considering replacing an old one, a warranty will protect you from unexpected outages. A reputable warranty company will be able to help you choose the right standby generator for your needs and budget.

One of the best warranties is a manufacturer’s warranty. This includes an industry-standard warranty, which covers both the unit and any replacement parts it may need. The best warranty will also include a free one-hour installation service.
