Automatic Transfer Switches

Automatic Transfer Switch Offers Optional 10 Cycle- or 10-Second Transfer Capability

Trayer Engineering Corp. has announced the immediate availability of  its latest Automatic Transfer Switches (ATS) in two distinct designs. Available in either 10-cycle high-speed or standard 10-second switching configurations, either ATS provides robust and reliable automated electrical switching per utility-defined criteria. The ATS will switch automatically to a separate line/way when the primary line voltage drops below a programmable level. Target customers include medium-voltage utility grids employing SCADA (supervisory control and data acquisition), smart grid or micro grid functionality.

Due to the high cost of energy failures and the increasing reliance of consumers on uninterrupted service, utilities are increasingly integrating SCADA and automation functionality into the existing grid—as evidenced by a significant trend among hospitals, manufacturers, universities and other premium customers who require more robust feeds, often involving ATS capability.

In response to this rapidly growing need, Trayer’s 10-Cycle ATS provides programmable, high-speed opening and closing of an electrical source at one-sixth of a second between multiple sources, using high-speed mechanisms and motor operators to auto-configure and reset the system. Alternatively, the 10-second “standard” ATS configuration allows the closing and opening of a source in 10 seconds in a tested, solid and field-proven mechanical way.

Both ATS options are available in standard four-way configurations, with two source ways and two three-phase VFI-protected ways.
