Notice of Intent to Award Sole Source to EATON

The Government intends to award a purchase order to the EATON Corporation on a sole source basis under FAR Part 13 - Simplified Acquisition Procedures for the purchase of services. This is for the purchase of a 'Transient Study'. The objective of the Transient Study is to properly size the snubber on the secondary (11.75 kV) side of each 2250 kVA voltage regulator cyclo-converter transformers feeding the port and starboard rectifiers of an unknown transmitter device.

The location of a snubber on the secondary of the transformer is unusual as they are commonly placed on the primary of the transformer to mitigate switching transients created by upstream vacuum circuit breakers (VCBs). The study will determine if a snubber is necessary at this location and, if the study results indicate a snubber is needed, complete specifications for the components shall be provided.

If it is determined a snubber is not required on the secondary of the voltage regulator, the application of a snubber on the primary side (4.16 kV) of the voltage regulator shall be examined in a similar way. This requirement was previously advertised via Request for Info (RFI) NIWC_Pacific_MKTSVY_19D886.
