Market Trends © ABB - Page 4 Why would utilities want to upgrade to a single-phase, solid dielectric recloser with electronic control? ? n Higher level of coordination n Higher interrupting rating n Eliminate oil from system n Communication capability

Features n Vacuum recloser with 2 nd generation magnetic actuators n n n © ABB - Page 5 n 10, 000 mechanical/load operations Integrated current sensor Near maintenance free design Advanced insulation technology Integrated control device Solid dielectric HCEP insulation medium n Compact / Lightweight n Environmentally friendly – no oil or SF 6

© ABB - Page 6 OVR-1 advantages n Integrated single pole design n Tripping and lockout can be done with hookstick from ground level, or from control panel (mechanical trip, electrical isolation) n Recloser can be shipped with potential transformer mounted on the pole frame n Can be utilized with one lift installation n Faster operation for better fuse saving n Higher creepage design than strictest IEC/ANSI standards n Modbus-DNP converter available for remote communications

OVR-1 Main Components n Hydrophobic Cycloaliphatic Epoxy (HCEP) n n n Hydrophobic surface properties improved over CEP Mechanical strength of epoxy Low leakage currents Lower flash over probability Better material = More reliable Improved pole design Higher creepage n Computer modeled for improved reliability (new technology) n 2 nd generation actuator design n Better design = More reliable n n ICD Recloser Control Win. ISD configuration n Easy to use n Improved control = More reliable © ABB - Page 7 n

OVR-1 Low Voltage Cabinet n n n © ABB - Page 8 n n n Compact light weight design Painted galvanized steel Integrated high energy surge protection in accordance with ANSI/IEEE C 37. 90. 1 – 2002 120/240 VAC input standard (48125 VDC input optional) Can provide Batteries for 24 hour backup power during loss of ac source power Integrated Capacitor assist for operating when battery discharged Lockout indicator light Heater

ICD Control Fully integrated magnetic actuator-based control including energy storage capacitors n Automatic actuator coil continuity check n Remote control via RS 232 serial communication port n Built in discrete I/O n Fault current indication n Continuous self-diagnostics of power supply, memory elements and microprocessors n AC or DC powered for flexibility n Accurate coordination – less co-tripping © ABB - Page 9 n
