8 Wants I dn t want t have t g t my substatin in rder t cllect inspectin and testing data I want my substatin t tell me when it needs t be maintained I want mre real time data n all f my substatin assets What technlgy is available that can help us with this?

9 Reduce planned maintenance withut sacrificing reliability Cllect inspectin data mre efficiently and ften Reduce utage needs t cllect testing data Cnvert t Cnditin Based Maintenance Triggers Reduce manual trips t substatins Cllect mre asset data that can be used fr data analytics Gals Better asses Asset Health insight Imprve wrk priritizatin and planning Imprved data quality & cnsistency Detect failure cnditins quicker Prevent catastrphic failures

12 Remte Substatin Inspectin System Prpsal Keep crews ut f harm fr emergency events Install a remte r autnmus inspectin system at the substatin The system wuld cntain a highly maneuverable high reslutin visual and infrared camera Replace manual physical inspectins with remte inspectins Yard walk dwn inspectins Thermal IR Inspectins Prvide peratrs and maintenance respnders immediate situatinal awareness Remte restratin after fault events Assess site cnditins during/after weather events Capture perating event data fr event analysis

13 Remte Substatin Inspectin System Abut 30% f the industry is at least cnsidering remte inspectin systems (visual & thermal) PTZ Visual & Thermal cameras Maintenance analytics will alert n ht spt and ther detectible cnditins

14 Prpsal: Replace mnthly, annual and 5 year testing and inspectins with cntinuus mnitring, alarms and predictive replacement. NERC Standard PRC mnitr and alarm fr: Batteries / Chargers High/Lw DC Supply Vltage Electrlyte Level Unintentinal Grunds Charger flat vltage String cntinuity Intercell Resistance f entire Battery Internal Cell Ohmic Values r Flat Current (must cmpare t baseline values) All alarms and mnitring paths must be verified nce a year r be autmatically mnitred.

16 Lightning/Surge Arrestrs Prpsal Replace 8 year Dble Testing with Leakage Current mnitring (LCMs), alarms, and predictive replacement. Use the remte inspectin system t rutinely measure the thermal signature f the LA. Reduce planned utages and cst f testing LAs Real time, Operatin Data: Cunts f high current cnductance events Cntinuus leakage current Rutine thermal signatures Prevent unplanned utages by trending data t determine replacement needs
