The ME/MK series metering units are outdoor, three-phase, pole-mounted metering racks rated for use on overhead line systems up to 34.5 kV (200 kV BIL). The ME/MK units are IEEE, CAN/CSA, IEC compliant.

APPLICATIONS
These metering racks are appropriate for use on overhead distribution networks.

ADVANTAGES

• Excellent metering characteristics. Standard confi guration includes class 0.3 metering accuracy units with optional High Accuracy and Extended Range class 0.15 CTs.
• The ME/MK metering units are suitable for use in 1, 2 or 3 element metering applications.
• Highest quality instrument transformers.
• Maintenance free, ensuring a long mechanical and electrical life.
• Partial discharge measurements exceed the IEEE, CAN/CSA and IEC requirements.

CONFIGURATION OPTIONS

• ME series with 3 CTs and 3 VTs.
• MK series with combined CT/VT units.

TECHNICAL CHARACTERISTICS

• Instrument Transformers:
  • ME series incorporate 3 current transformers mounted vertically and 3 voltage transformers mounted horizontally.
  • MK series incorporate 3 combined transformers mounted vertically.
• Metallic rack:
  • Standard structure made of lightweight aluminum with pole diameters available from 8" to 14". Optional galvanized steel structures and/or other pole diameters are available upon request.
  • Designed to mount on poles in an upright position.
  • It includes two galvanized steel mounting bolts for attaching the metering unit to the pole.
• Terminals:
  • The Current and Combined transformers primary terminals are flat, tin-plated copper with standard NEMA 2-hole pattern suitable for various size conductors. The VT primary terminals are M12 stud with a compression type lug for #8 - #2 AWG conductors.
  • The secondary terminals are pre-wired through protective conduit to a 10 position test switch in standard red/black colors mounted to the rack.
• Total weight varies depending on the selection of the instrument transformers.
