Diesel Generator Automatic Transfer Switch

In today’s society, access to electricity at any time is crucial to the daily production and operation of enterprises. Natural disasters, blackouts due to brownouts, high demands on the grid, and more are all reasons for power outages. Because of this, many businesses maintain business operations at any cost, even when the local power system fails, or implements a policy of power rationing. So, what will keep businesses at the forefront? Install a backup diesel generator with an automatic transfer switch.

So, what is an automatic transfer switch (ATS)?

Automatic switch (ATS) refers to the automatic switching from public grid equipment to backup diesel generators when the grid suddenly loses power. The existence of this intelligent automatic transfer switch means that in the event of a power outage, the backup diesel generator will automatically start without supervision and human intervention. In addition, due to the existence of the diesel generator, after the power supply of the public grid is restored, it can be automatically shut down without manual shutdown, which realizes the automatic shutdown of the diesel generator and transmits power to the public grid.

Why is an automatic transfer switch (ATS) necessary?

In today’s society, many machines and equipment rely heavily on electricity. Once a power failure occurs, precision instruments or equipment may be damaged. If there is no automatic transfer switch (ATS), the diesel generator needs to be started manually during a power outage, which will cause a waste of time and manpower, and can no longer meet the requirements of a modern intelligent society. Especially for some enterprises that cannot delay the restoration of power supply, they should be equipped with generators with automatic transfer switches. ATS is one way to keep your business and customers safe with electricity.

However, backup diesel generators are installed and use automatic transfer switches (ATS), which guarantee seamless switching of power during momentary power outages. Although diesel generators are equipped with manual transfer switches, the generator must be turned on and off manually. Doing so will bring trouble to many companies and affect efficiency. For example, if some cold chain warehouses suddenly lose power at midnight, then when you go to work in the morning, you may find that a lot of your food has become smelly and must be thrown away, causing irreparable losses.

In general, the following businesses will rely on automatic transfer switches (ATS) for diesel generators:

Construction sites, schools, food services, hotels, healthcare facilities, shopping centers, factories, and warehouses.

What benefits can ATS bring? In the next step, we will share the advantages of installing an automatic transfer switch (ATS).

Safety

Every entrepreneur knows (or should know) how important security is to running a business. The unsafe power supply also has many hidden dangers. For example, in addition to damaging the company’s image, any incident that causes the safety of employees and customers is a serious liability issue. Diesel generators fitted with an automatic transfer switch (ATS) reduce these risks by ensuring that the generator starts quickly and automatically in the event of a power outage and returns power to the business. Regardless, safety has always been one of the main reasons businesses choose to invest in backup diesel generators.

Reliability

When it comes to reasons to buy a diesel generator, reliability is probably the most important for most businesses. For many businesses, it is especially important that electricity will continue to be supplied to the business uninterrupted. Access to electricity is key for many businesses. For example, in a medical facility, patients may not have access to the medical equipment they need. The Automatic Transfer Switch (ATS) ensures that power is restored immediately, no matter what the cause of the outage.

ATS is still required even in businesses that do not have such a critical power supply.

Simple

No matter how complicated the business is, if you have a diesel generator equipped with an automatic transfer switch (ATS), many businesses can restore power immediately during a power outage to ensure that the normal production and operations of the business will not be affected by the power outage!
