A waste water treatment facility in the northeast United States found that poor voltage regulation was a significant problem for their equipment. The facility decided to remedy the situation with a voltage regulation MITS, resulting in fewer equipment issues and improved reliability. 34.5 kV Fused Disconnect Switch

This application involves a dedicated mobile application for the customer. Fueled by the need to respond and react to potential emergency situations, this mobile MITS provides the customer the ability to transform voltage. Used in conjunction with a mobile genset, voltage is generated at 480V and stepped up to a voltage of either 4160Y/2400 or 2400V delta to supply power on an emergency basis.

Value proposition Fifty percent savings on future relocation costs, 15 percent savings over conventional design, 25 percent savings in space, and increase in cash flow due to a quickly commissioned substation. Primary Metering Primary Metering Compartment Compartment Configured for supplying electrical loads for sites that extract ground 14,400–120V VTs 14,400–120V VTs water embedded with natural gas, this MITS application is a different way of building substations for the mining industry. Using a skid- based platform, the MITS reduces the footprint and can provide a cost savings over a typical installation. Eaton’s modular substation is 50 kVA Station Service Transformer designed to be relocated to a new site after its service is completed HV: 14,440GY at the existing site. The ability to move the entire substation without LV: 240/120V complete disassembly can provide customers with substantial benefits over conventional substation installations. Figure 5. System Schematic Viewing loads and status of equipment in harsh, remote environments often requires a long drive across difficult terrain. Eaton provides RTU cabinets populated with IEDs and SCADA equipment to meet most specifications. This contributes to cost and time savings for maintaining valuable equipment.

Value proposition Modular design can be used at many locations, is completely integrated, provides on-board spill containment, and is transportable. 15 kV Recloser (1) Three-Phase NOVA Driven by the need to cut the cost of installed substations and to (Solid Dielectric) 15 kVA Station create a modular design concept, this customer turned to Eaton’s Tamper-Resistant Service MITS solution. The conventional substation consisted of overhead Outdoor Enclosure Transformer distribution, transformation, and feeder protection. In addition, each HV: 13,800GY LV: 120/240V substation required the site to be prepared for oil containment in the event of a leak. In this example, Eaton provided solutions to the customer’s requirements and allowed the use of this modular solution at several sites throughout the electrical grid. Figure 7. System Schematic

Recloser (1) 35 kV, 200A Value proposition Three-Phase NOVA (Solid Dielectric) Substantial saving over conventional substation design, 25 to Tamper-Resistant Outdoor Enclosure 30 percent savings in project management, and over 60 percent smaller footprint than conventional substation design. Installed in the western part of the U.S., this application combines two MITS skids that will provide dual functionality. Initially, the skids will step up voltage from 13.2 kV to 34.5 kV, and distribute 15 kVA Station Service Transformer 48 Vdc Battery System voltage onto the transmission lines. At some point in the future, with AC Charger the customer plans to use these skids in the reverse fashion and HV: 34.5GY/19.9 kV step 34.5 kV down to 13.2 kV. Included with each skid is an Eaton LV: 120/240V differential protection relay used to trip the NOVA recloser and an upstream device.

L Value proposition Significantly smaller footprint than conventional substation design, safe and secure design requires no fencing, and one point of contact for entire substation. The heavily wooded terrain of a 13.2 kV to 4 kV metro area provided challenges to the utility that served local estate homes. Unit substations serving the area were several decades old, 4 kV Recloser had become heavily loaded, and lacked needed and overlooked maintenance. A new Eaton MITS was the best option.

Eaton mounted Transformer and pre-wired a 5 MVA transformer, three pad-mounted regulators, Single-Phase a station service transformer, switchgear, and controls on a single HV: 7620GY LV: 240/120V structural steel platform. The customer pre-installed the ground 15 kV Reclosers (3) grid, the MITS foundation, the incoming circuits, and the outgoing circuits. Total field install time of the MITS assembly was less than four hours. Power to a town and surrounding community was restored in record time, and at a total installed cost 25 percent below conventional methods. Figure 15. System Schematic

the existing landscape. 25 kVA Station Service A substation was needed to serve a remote industrial load. Because Transformer HV: 24,940Y/14,400V of the unique transformer design, it was acquired through a third LV: 240/120V

party and installed on a separate structural steel platform along with Skid 2 a high-side recloser, which serves as a switch and protection device. To achieve cooling requirements, fans were required on the transformer. (The external transformer cooling fans no longer make Figure 17. System Schematic the assembly tamper-proof; therefore, fencing is required.) A second structural steel platform was used to pre-install and test three single- phase, pad-mounted voltage regulators, switchgear, a control center, and a station service transformer. The platforms were interconnected at the job site and the completed assembly, as an integrated whole, did not affect the integrity of this finished product. Surface grading to level the area would have been required for a concrete foundation. Instead of the concrete foundation, steel pillars were installed at weight-bearing points under the entire MITS assembly to elevate the structure from ground level.
