Figure 3 – Diagram illustrating multiple automatic double-throw transfer switches providing varying degrees of emergency and standby power Such an arrangement, using multiple automatic transfer switches, is shown in Figure 3. It is sometimes referred to as a “main-tie-main” configuration.Īvailability of multiple utility service systems can be improved by adding a standby engine-generator set capable of supplying the more critical load. The arrangement shown in Figure 2 can represent the secondary of a double-ended substation configuration or a primary service. Multiple transfer devices of lower current rating, each supplying a part of the load, may be used rather than one transfer device for the entire load. The automatic transfer switch is one of them, because, as the name implies, it is a component that allows the automatic switching of the energy source that. It may be desirable to locate transfer devices close to the load and have the operation of the transfer devices independent of overcurrent protection. In the enterprises where power cuts are frequent, where uninterrupted power is needed and where interruption can cause huge. A Power Transfer Switch provides a simple, cost-effective means to add automatic power fallback capabilities and power redundancy to single power inlet network. NZ7 Series Automatic Transfer Switches for hassle free changeover when the main supply is down. An electrical or mechanical failure of the electric power distribution system within the building PTS is a wholly owned subsidiary of Power Technologies that offers an extensive range of transfer switches designed to transfer electric loads seamlessly.An overload or fault tripping out a circuit.Automatic Transfer Switch (ATS) is used to transfer a power supply from its.

The arrangement shown in Figure 2 only provides protection against failure of the normal utility service.Ĭontinuity of power to critical loads can also be disrupted by: Software for designing various configurations of automatic transfer switch systems: driven by contactors (CEM, CES), MCCBs with motor operators (EB2) or. Figure 2 – Two-utility source system in which any two circuit breakers can be closed Under these conditions, the cost of an extra circuit breaker can rarely be justified. In this case, the tie circuit breaker can be eliminated and the two circuit breakers act as a transfer device ( sometimes called a transfer pair). If the utility will not permit dual or totalized metering, the two sources must be connected together to provide a common metering point and then connected to the distribution switchboard. If the supplying utility will not permit power to be taken from both sources, the control system must be arranged so that the circuit breaker on the normal source is closed, the tie circuit breaker is closed, and the emergency-source circuit breaker is open.
