Trayer Engineering Corporation announces the PNP Series of primary network protection for spot networks. Trayer’s PNP is designed to assure cost effective and reliable service to critical and sensitive loads requiring uninterruptible primary power delivery.

The self-contained PNP switchgear provides simultaneous connection of the load from two independent feeders. Should a fault be detected on either of the feeds, a vacuum fault interrupter (VFI) disconnects the spot network from the fault while seamlessly providing uninterrupted primary power to the load. When the fault condition is cleared, the unit automatically reverts to its dual-feed operation.
According to John Trayer, President and CEO of Trayer Engineering, “PNP is the ideal upgrade solution that can easily replace a standard ATS whenever uninterrupted primary power is desired. In addition, the dual-feed configuration results in a stiff source to the load that can eliminate a host of common power quality problems.”
PNP Series units are offered with 5kV, 15kV and 25kV ratings in both padmount and submersible configurations. All feature Trayer’s signature welded 304 grade stainless steel, storm-hardened construction and SEL grid protection relay controls.
