An automatic transfer switch consists of an electrical power control device that reroutes electricity under certain power conditions. It enables the safe switching of power from one source to another. Consequently, this ensures a safe and reliable transfer of power while minimizing the risks of fire, damage, or back feeding of power to the utility lines.

An ATS ensures continuity of power to the load. However, the time between loss of power in the utility line and the time the load is connected to the alternative power source remains critical in some applications. For example, a power loss for a few seconds is unacceptable in some hospitals or with emergency equipment. In some of these installations, an intermediate power supply is utilized. These include the battery-based inverter or UPS power to fill the gap between the loss of power and connection to the generator power.

Advanced ATS devices may have the ability to detect the voltage dips characteristic of power failures and automatically start the generator before the utility power goes off completely.

Consumers need to ensure that the ATS will have adequate capacity to handle the generator power. Things to consider include the voltage rating, continuous current rating, and type of load. In addition, consider the mode of transfer, desired transfer time delay, ATS style, and more.

The four main categories of ATS devices are defined by the following transition modes.

Open-transition: The open transaction mode of operation disconnects the primary power before connecting the power from the secondary source. This break-before-make operation means a short duration when there is no connection to either of the power sources.

Fast closed-transition: The ATS is based on the make-before-break switching operation. It parallels the two supplies for about 100 milliseconds after which it disconnects one of the sources. This operation ensures that the load is never disconnected from power.

Soft closed-transition: The soft closed-transition transfer synchronizes generator power with the utility line and then transfers the load from the utility to the generator. When transferring the load back to the utility, follow a similar process.  In this case, the generator output slowly decreases until completely off.

Sub-cycle transfer: These are based on semiconductor switches and are the fastest automatic transfer switches. Upon detecting a power failure, the ATS transfers the load to the other source within the first one-quarter of the electrical cycle. This ensures no power interruption to the load. Sub-cycle ATS devices are the most complex and expensive compared to those using mechanical switches.

Since consumers may not have all the necessary technical knowledge to choose the correct application, it can be a good idea to hire a qualified electrical contractor to select the correct sizing and installation.

One of the advantages of Li-Fi is its ability to function in electromagnetic-sensitive areas such as in aircraft or nuclear power plants, without causing interference. Additionally, Li-Fi signals cannot travel through walls, a welcome feature for many users who wish to increase their digital privacy, although this comes with its obvious drawbacks, such as difficulty in creating “blanket” wireless coverage.

Lighting fixtures can be a great addition to your household especially if you’re looking to improve your home’s appeal. Dim or flickering lights can be frustrating to deal with and can cause a real headache. Turning the lights on to only find yourself surprised with weak light bulbs can be inconvenient. And when it comes to your kitchen and bathroom, lighting fixtures are so beneficial since they see the most usage in your home. With poor lighting efficiency, you will see a decline in functionality for either room. Lighting is always going to be a key component for your home and that is why it is important to take care of lighting issues. When you’re looking make upgrades for your home, lighting fixtures should be at the top of the list.

Track lighting is a great option for homeowners who are looking to increase both the appeal and visibility of their bathroom or kitchen. Since track lighting is fairly easy to install, it can become an immediate update to increase the degree of illumination for your home. Track lighting will also allow you to point lamps in any direction, increasing the level of customization of lighting fixtures that you can take advantage of.

One of the lesser lit areas of your bathroom or kitchen is probably around your cabinets. It can be frustrating trying to find spices or even towels without enough lighting surrounding it. A helpful lighting installation is adding one under the cabinets. This is the best solution to this problem and in the meantime, adds an ambiance to the kitchen and bathroom areas of your home.

Feeling classy? Finding unrivaled lighting fixture.
