What Are Automatic Transfer Switches And Why Are They Important

Image result for What Are Automatic Transfer Switches And Why Are They Important

Automatic transfer switches or ATS are wonderful pieces of electric marvel that, when placed between two sources, help in load sharing. It means that when the supply is short in one source, that’s basically the primary source, the switch automatically throws power to the backup source to allow a disruption-free work environment. When installing one for your company, it is wise to consider supply and installation companies like Stanex for the fact that such companies offer utmost customer satisfaction and marvelous maintenance services.

Types Of Automatic Transfer Switches

Automatic transfer switches are of 4 types and you can always choose the one depending upon the load that you need and the dimensions of your property (commercial or residential).

  1. Open Transition Automatic Transfer Switch – This transfer switch is basically renowned for its capacity to prevent the back feeding of current from the primary source into the supply line. It is because this switch cuts contact from one source for 1/6 of a second before establishing automatic contact with the backup one
  2. Closed Transition Automatic Transfer Switch – Abbreviated as CTTS, this transfer switch works on the same principle as that by open transition transfer switch, but only that the cut off time is less than 100 millisecond. Nathless, despite there’s a cut in current supply for the purpose of avoiding back feeding, the process is so quick that the systems do not shut even momentarily. Also, these transfer switches need monthly testing for safety.
  3. Soft Loading Automatic Transfer Switch – Abbreviated as SLTS, this transfer switch is capable of transferring load between any two sources while curtailing the voltage transient to a minimum.
  4. Static Transfer Switch- Abbreviated as STS, this is a static automatic transfer switch that makes use of silicon-controlled rectifiers for the purpose of transferring load between the two involved sources. It offers load transfer from one source to the other within 1 quarter cycle of the supply power frequency. As a result of which these switches can control even two completely independent load sources.

3 Advantages Of Automatic Transfer Switches That You Must Know About

The following 3 advantages make ATS what they are.

  • Reliability Of Power – When you have automatic transfer switches installed, there’s not going to be power cut because your backup generator will effectively jump into action.
  • Guarantee Of Safety – Automatic transfer switches handle load transfer between generators. Which means you don’t have to physically pair a generator with a backup supply during a power failure. This makes things safer.
  • Simple Operations – Since the backup power is restored almost immediately, it gets pretty simple to keep the machinery working. Also, your generator is not exposed to any risk of damage.
