With an aging electrical infrastructure, sites are making capital investments to replace aged electrical assets. This is exactly what the Naval Research Lab (NRL) is in the process of doing. NRL is the laboratory for the United States Navy and Marine Corps. They provide research on plasma and space physics, material science, and electronic warfare to name a few. With the vast number of technological advancements coming from this one site, it became imperative that its local electrical infrastructure be upgraded to meet current and future electrical demands.
The project consisted of three unit substations feeding buildings on the NRL campus. VanTran provided two 2500KVA padmount transformers, two 5 MVA substation transformers with Neutral Ground Resistors, and two 750 KVA substation transformers (one of which featured three secondary voltages) close coupled to MV Switchgear and LV Switchboards.
The project was a perfect fit for VanTran because of the requirements for full stainless steel construction, compliance with the IEEE C57.12.29 costal paint specification, and the three secondary voltages on one of the substation transformers.
