The unit also features the company’s patented tri-phase visible disconnect switch, manual trip indication and is offered with either liquid or gas dielectric mediums. To optimize performance, the switchgear employs custom, compact vacuum-bottle contact and industry-standard SEL automation and overcurrent controls. Rated at 600A continuous current, the gear is capable of up to 10,000 load break operations at full load and 65 operations at 12.5kA fault current.
The switchgear in operation at Newport is the Trayer 3805 Series VFI.
“In so doing, we provided Central Lincoln with a one-of-a-kind solution that will have industry-wide appeal for reliable, high-performance automatic switching far exceeding the capability of standard switchgear solutions.” “Working closely with Central Lincoln, we fine-tuned the standard SEL relay package, modifying its firmware to unleash the relay’s untapped capability of simultaneously protecting four different three-phase circuits,” said Michael Daish, the company’s vice president of sales and marketing. In addition to the gear’s ruggedized physical and electrical attributes, this particular application represents the first known use of the industry-leading SEL-487E relay for distributed I/O automation functions beyond the scope of its original design. The facility’s serving utility, Central Lincoln People’s Utility District, installed Trayer 3805 Series medium voltage switchgear to protect their distribution system from a failed transformer or other system fault/overcurrent condition. Newport, OR is the site of NOAA’s new Marine Operations Center-Pacific, a 24/7/365 mission-critical facility with global maritime responsibilities. Trayer Engineering Corporation highlights a new, cutting-edge distribution automation application with the publication of its latest case study.
