Designing, building and validating power grid solutions has never beeneasy. Today, growing complexity of the modern electrical grid can increaserisk and cost just to ensure the integrity of the system. Adding to thisintricacy is a growing number of manufacturers offering a wide arrayof products, ever-changing standards and product test requirements,

and new technologiesall competing for a place in the Smart Grid future.Grid operators and designers must balance these technological advanceswith the critical need for maximum system reliability.

Today, both large and small electrical power distribution organizationsare looking for the flexibility to choose their power system reliabilityintegrator and service support team, including warranty return andapplication assistance.

The importanceof managing thisinteroperabilitycomplexity was clearlyon display duringthe 2013 Super Bowl.Most of the powerindustry watched thedarkness in surpriseand concern. As theinvestigation followed,many industry leaderswere forced to consider:

Interoperation betweenthe power system andequipment; in this case,a protection system

Interoperabilityof sub-systemsThe design of an integratedsystem should be able todefine sub-system requirementssuch as:

Electrical ratings

Thermal ranges andtheir impact on ratings

Compatibility

Environmental

Sustainability

Manufacturability

Each of these impactsthe design of the system.

Interface requirements forthe sub-system include timing,voltage levels, circuit designfor surge immunity, mechanicalimpacts and others.

Eaton remains committed tooffering full control integrationincluding necessary:

Sensor design, thermal

ranges and accuracy Sensor interfaces to the

power system and apparatus

Automation interfacesand the power to run them

Apparatus/control processsignaling

Power sources and theirconnections to the system

Cabling and reliability toelectrical and environmentalstresses

Cabinetry and climate control

Continued delivery of addedfunctionality for protectiveand emerging automation

Testing developed

to industry standardsIndustry organizations suchas the Institute of Electricaland Electronics Engineers(IEEE)and the InternationalElectrotechnical Commission(IEC) have established minimumstandards for reclosers, voltageregulators, switches, and faultinterruption devices. Clauseswithin them establish systemconsiderations or type tests thatverify the interdependencybetween apparatus and thecontrolling devices. Not only dowe understand and fully adhereto these standards, we arepart of many standardsdevelopment committees.

Examples of system-leveltesting include:

Reclosing and overcurrenttrip calibration

Time-current tests

Minimum tripping currents

Surge withstand tests

Fast transient surgesand simulated surgearrester operation

These tests are designed

to verify design integritysuch as the interdependencybetween the apparatus andthe control, and will oftenpoint out vulnerabilities whichneed to be addressed beforea design is released. Standardreflect that these tests beperformed by the supplier.The supplier with the mostcomplete understanding ofthe entire system and systeminteractions has the greatestopportunity to optimize systecapability and performance.

Today's Smart GridThe electric powergrid is said to be anengineering marvel,arguably the largestand most complexmachine in the world;a machine with apersonality, capableof delivering uniqueeffects to anythingconnected to it. Fromsurges, elevated faultcurrents, asymmetry,changes in fault orload current direction,to high or low voltages,or induced or radiatedfields, Eaton has theexpertise to accountfor power systemnuances those

defined in the industrystandards, andothers that we havelearned over decadesof interoperabilityresearch.

Innovation in apparatus

and controls is continuous

Recognizing the need toempower users to customizelogic in their controls, Eatondeveloped an industry-leadinggraphical customizationenvironment we call the IdeaWorkbench. Today it is usedand modified to solve someof the most complex needs forcustomers in communications,protection and reconfigurationschemes.

There is a continuing trendin adding voltage sensors toequipment as an inexpensivesensor node on the powersystem. The sensors can beembedded in the equipmentitself to simplify installation.However, many compromiseaccuracy to accomplish this.The Eaton Internal VoltageSensor (IVS) on reclosersprovides accuracies
