All ATS units should meet the UL 1008 safety standard and the various National Electric Code (NEC) standards recommended by your specifier and gen set supplier. These controls can be either adjusted by the operator or fully preprogrammed at the factory. It also times a cool down period when the engine has been under load. The ATS also provides a timer so the engine runs long enough to warm up fully.
It also returns the load to the utility line when utility power is restored.
TRANSFER SWITCH GENERATOR
It transfers loads to the gen set when the engine has sufficiently warmed up and the generator has reached operating voltage and frequency.
TRANSFER SWITCH ANDROID
Who can transfer Android owners - Wireless transfer: Android 4. Plus, Smart Switch helps you find your favorite apps or suggest similar ones on Google Play. It senses when voltage on the utility falls below predetermined limits, then initiates gen set start-up. Smart Switch gives you the freedom to move your contacts, music, photos, calendar, text messages, device settings and more to your new Galaxy device. The ATS provides several control functions for gen set operation. It operates faster than circuit breaker transfer switches, which reduces transfer time. The contactor type is simpler design that is electrically operated and mechanically held. The circuit breaker type has two interlocked circuit breakers, so only one breaker can be closed any anytime. There are two types of automatic transfer switches, circuit breaker and contactor.
In these cases, an optimum time must be decided upon, depending on the various loads. However, switchover from utility to gen set need not be done immediately. They need time for the flux to decay eliminating the possibility of gen set or motor damage.Ĭonversely, equipment such as computers with uninterruptible power supply (UPS) systems must also be backed up in case outages exceed the UPS capacity. In this Switch system transfer guide well take you through all the steps to transfer all your data over to your new Switch OLED, Switch Lite, or regular Switch from another Switch console. Motors, when disconnected from power sources, temporarily maintain voltage because magnetic flux continues to be produces by the spinning rotor. Provisions must be made for these short duration overloads in the ATS and protective equipment. Resistive heating loads can consume from three to five times rated currents. Motors starting can consume six to 10 times normal continuous current, so can tungsten and fluorescent lights.
TRANSFER SWITCH WINDOWS
Not only would you need multiple lengths of extension cords and need to run cords through open windows or doors, but you will also only be able to power appliances that have a standard plug. Type of load determines the inrush current. Without a transfer switch, you would have to string extension cords from your generator outside to your appliances inside. The main consideration is continuous current, but inrush and interrupt currents are often overlooked. Switchgear sizing is determined by four factors: Continuous current, inrush current, interrupt current and withstand current. The customer also cannot degrade the safety interlocks and protection devices on the power network. Utilities require that customer connected equipment (including gen sets) must not cause disturbances or degrade the quality of service to other customers on the line. Occasionally, gen set applications require paralleling of generator power with the utility power. The unit must be sized correctly for the loads it serves as well as have the correct protective devices. Many considerations affect ATS selection. This switch must handle overloads for a short period of time while the proper protective relay begins operation. It provides safety to the gen set operator and protects the electrical service and the utility. Proper transfer switch operation is critical to the whole power system.
