Information On A Power Transfer Switch

Image
          A power transfer switch is needed if you want to switch from a primary power source to a secondary or tertiary power source. It is also employed in many electrical power distribution systems across the world. You can see transfer switches in areas where there are emergency power generators used as backup power for utility source.

Generator Transfer Switches Help Protect You

    If you are experiencing frequent power outages in your area, or that your area is susceptible to severe weather,   generator transfer switches   can help you safely power your home or business. This power-supplying device can provide comfort, safety and security during power outages and emergencies, and can be installed temporarily during these situations. It must be connected properly to protect electrical utility workers, family members and property. Improper connection of the device and the power-switching device could void your homeowner's insurance in case of accident or injury. Improper connections also allow electrical current from the generator to short circuit with utility line current when powered is restored. This can cause a fire in the electrical system. 

Automatic Transfer Switch - Power Within Your Hands

     Due to the needs of electrical shifts, the automatic transfer switch has been developed. Switches are the things that connect the operator from the equipment he is operating. Often this also enables the operator to declare if energy is available or not.  This is because this minute device has the capacity to break or divert circuit and it can also decide whether preset or not, unto which energy supplier will the electricity come from. The electromechanical type is the most common form of this device, which is connected to one or more electrical contacts. The contacts can be either closed or open. When closed, the contacts are touching and electricity is flowing freely between them whereas open contacts are not at all connected to each other and are not producing energy.

Test That Transfer Switch

If you've been putting off conducting maintenance checks, you could be doing more damage than you think. An automatic transfer switch (ATS) is a critical part of any emergency power supply system (EPSS). The ATS is the device that selects a power source—either normal utility power or standby generator power—and conducts the power to critical loads. The NFPA, Joint Commission on Accreditation of Healthcare Organizations (JCAHO), and all major ATS manufacturers publish literature calling for the monthly test of ATSs, yet many facility owners ignore these guidelines and refuse to perform the tests. There are good reasons for both the monthly-test requirement and for the reluctance of many operators to comply.

Transfer Switch Jeopardizes Hospital Safety

 Poor heat dissipation from control transformer leads to fire in transfer   switch . After a fire broke out in a hospital's 1000A automatic transfer switch (ATS), everyone involved was left searching for answers. Again and again, the same question was asked: Why would a fire start in a switch that operated without noticeable incident for several years? The answer: poor heat transfer.

Static transfer switch helps keep NASA in space

               For more than 50 years, Tensolite, St. Augustine, Fla., has been the world leader in the design and manufacture of custom high-tech wire. NASA, Boeing, and the military rely on Tensolite to provide light, high-speed cable and wire to transfer critical data. Prior to 1994, Florida Power & Light (FPL) served Tensolite, a 1.2MW user, by one substation 10 miles away. Furthermore, pine trees surrounded the distribution lines to the company. With such a precarious electrical setup, it's no wonder Tensolite averaged 50 to 60 outages a year.

Transfer Switches Simplified

Practical tips for understanding and installing these devices in residential applications As backup power sources become more common in residential construction (Photo 1), many homeowners have learned about the needs and benefits of transfer switches. They know in the event of an electric utility power supply outage it is at the very least desirable to power up selected circuits in a service entrance panel to provide limited light, heat, and refrigeration. Having the option of operating a double-throw switch — or sitting back and doing nothing while the switch operates on its own — is a very appealing and safe option.
