Not only does it move the load to the backup generator, but the backup generator can also be ordered by an ATS to start (provided the generator was initially in standby mode). This depends on the voltage on the primary supply being controlled. When the generator is on and supplying temporary electricity, the shift switch is responsible for isolating the backup generator from the electrical utility.

When utility power returns for a minimum duration, the shift switch will transfer the house back to utility power. While doing so, after another specified period of “cool down” time with minimal or no load on the generator, it will order the generator to turn off.

Advantages of Installing Automatic Changeover Switches

• When the power goes off, it saves you from the hassle of frequent manual line changes. It can be catastrophic to deal with a manual generator hookup, particularly in the dark! A transfer switch meets all your needs on its own, completely eliminating the dangers associated with an outage.
• A transfer switch that has been properly installed protects your home or company. Improper ties mean that when power is restored, the electrical current from the generator will short circuit with utility line current.
• In industries where everybody is busy expanding their market, no one wants an extra job and any time the power goes off, they have to change the power line from the main supply to the generator supply. If you lose access to power for any reason at all, your company stops dead in its tracks.
• And while a generator can alleviate this a bit, you have to manually connect your generator to the operations you wish to restore without a transfer switch. Not only does this chore eat up tons of time, resulting in downtime, it also limits your generator’s work.

An automatic changeover switch, also known as a transfer switch, is an electric smart switch which is designed to transfer electricity from the commercial power supply grid to a local generator in case of a power outage to your house. 

IT’S WORKING :

Changeover switches have simpler working mechanisms. Typically, they are connected directly to the local generator, commercial power grid or the power line and the residence or a commercial site. When faced with a power outage, the complex owner can simply switch over to  the generator by the means of a changeover switch. This mechanism is followed by a manually operated changeover switch. 

Whereas, an automatic changeover switch will automatically switch over your house’s power when a power outage occurs. 

ITS OPERATION: A house equipped with a standby generator and an automatic transfer switch is faced with a power outage, the transfer switch will cue the generator to start.

The main function of an automatic transfer switch is to break the house’s connection to the electric power grid supply and connect it to the standby generator. The generator, then will supply power to the load, still not being connected to the main utility line. It is important that you isolate the generator from the distribution system so that it remains protected from overload in powering loads.

The utility power will gradually return for a minimum time and in that length, the transfer switch will transfer the house’s electric load back to utility main line and cue the generator to turn off after its “cool down” period with zero load.

WHY DO PEOPLE OPT FOR CHANGEOVER SWITCHES?

Over the couple last decades, changeover switches have become more and more popular, latter has still been rising. Most of the time, the reasons behind power outages have been weather conditions such as hurricanes, winder storms, thunderstorms, etc., while other outages have been reported to be caused by hardware failures.

FOR HOUSEOWNERS:

The mere obstruction caused by frequent power failures became an ornery problem. Your electronic devices are switched off abruptly and that itself is a threat. More so, if you live somewhere up north, recurring power blackouts can render your heating systems to turn off, making it difficult to stay warm during winters. This elicited a need to install generators with changeover switched from many a property owners. That helped homeowners to overcome the periodic trouble of blackouts as they were still able to operate their electronic devices when the power supply is interrupted.

FOR BUSINESSES:

For commercial usage, for example- businesses, changeover switches work as a boon. Sudden power blackouts are the most exasperating scenarios for big businesses. As most of the commissions are electronic, random electricity cut off results in immediate halt to all the activities, frittering time, labour and monetary resources away. Hence, automatic changeover switches are highly advised so that none of the activities are hindered saving money, time and resources. They simply switch over to fall-back generators and keep the power flow going.

HOW IT HELPS CURB GLOBAL WARMING?

To fully grasp the need to install a stand-by generator along with changeover switches, first we need to understand the dread of power outages

Power outages, also called power cut, blackout or  power failure, occur when there is a loss of electrical power network supply due to short circuits, cascading failures or fuse breaker. Power failures result in large scale blackouts and may range from a building, to a lane, or even to an entire city. 

Locations like hospitals, mines, sewage treatment plants are the most critical sites for power failures as they not only risk total blackout but also jeopardize environment and public safety.

Concerning its obvious threats to environment, one can look back at the Northeast blackout of 2003. 

In August, 2003, North-eastern United States and some closely located Canadian Province experienced the most widespread power blackout lasting from more than five hours at some locations. The blackout was caused because some overgrown trees got mingled with high voltage electric supply cables. Then followed a software crash that affected nearly 55 million people in north-eastern parts of the United States and Ontario province in Canada. The energy waste was unimaginably high.  The waste meant so much more contingent to the fact that our environment suffers a great deal in production and even distribution of electric supply.

The rather complex system of generation, delivery and end users is referred to as electric power grid. 

The three major resources used in generation of electricity are natural gas, nuclear power and coal. The fact is not avoidable that the burning of fuel causes air pollution and leads to emission of greenhouse gases such as CFCs and other harmful contaminants like sulphur oxides, etc. These pollutants rise up in the atmosphere and hampers the ozone layer causing an overall temperature rise on earth, i.e. global warming. 

In cases of blackouts, the amount of electrical energy squandered not only causes great monetary causes but also evinces the manipulation of fuel resources and its dreadful aftermath. 

Using changeover switches to tackle the problem of power outage is not just wise but advisable as well. They can automatically switch over the power supply from the electric power grid to a stand-by generator causing minimum energy loss.
