MetPod Availability�

•  MetPod available now for 8 kV - 36 kV •  Fiber MetPod available now for 8 kV - 36 kV •  MetPod Lite available now for 4 kV - 36 kV •  Higher voltage MetPods depending on requests

•  Pricing- –  Competitive with conventional solutions in 1-9 pc quantities –  MetPod Lite lower cost than MetPod –  Very attractive MetPod Lite pricing in large quantities (>10,000

units)


Slide 14

Applications

–  Energy theft –  Feeder monitoring –  AMR, AMI, SCADA


Slide 15

MetPod Applications�

•  Feeder monitoring (can communicate with SCADA system) –  Power quality, Harmonic pollution –  Fault location to improve recovery time –  Identifying system losses –  Load balancing

•  Harmonic load monitoring within privately owned distribution equipment –  Identify incipient faults in equipment, incorrect wiring, design

improvements thru harmonic signature analysis

•  Power theft (stand-alone data collection or AMI tie-in) –  Monitoring MV line to identify power theft locations –  Permanent assets or liquid capital (temporary installations)


Slide 16

MetPods meet Application Needs�

•  Feeder monitoring (communicates with SCADA system) –  High bandwidth for harmonics (up to 80th) –  High accuracy to identify small losses –  Real-time updates of instrumentation values –  MetPod CT can measure <1 A to >20 kA in one device

•  Harmonic load monitoring within privately owned distribution equipment –  Fiber MetPod provides real-time waveforms at high bandwidth –  MetPod is compatible with metal-clad installation

•  Power theft (stand-alone data collection or AMI tie-in) –  MetPod provides metering accuracy at 0.1% of rated line current –  MetPod Lite cost is low enough to justify system-wide deployment –  FMI is actively working with AMI vendors
