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

Feeder Meter for underground cable installations�Dead-tank MetPod�
• MetPod core technology encased in grounded metal enclosure for safety
• Standard URD cables and termination hardware – Hard connect to high voltage for best accuracy – Utilize existing bus ports or splices – Short flexible cable run allows positioning of
MetPod to minimize mechanical loading • Hinged current sensor on umbilical clamps around
current carrying elbow/cable • Dead-tank MetPod electronics identical to overhead
feeder meter electronics • Provides accurate V, I measurements, powered off
HV conductor potential • Pricing comparable to MetPod classic
