The CMV transformer is designed for padmounted distribution transformer metering. It is available in two external designs, tapered bottom and wide bottom, for adaptability to a variety of mounting arrangements. Both designs can be mounted directly over the ILV terminals of pad mounted distribution transformers.
- 600 Volt Indoor or Outdoor
- 10 kV BIL
- 25 through 60 Hertz
- Primary Amperes 100-4000
- 3.5 in. x 4.5 in. oval window
The CMV transformer has an oval shape ring-type core and
fully distributed winding assembled around a glass-filled polypropylene window liner.
Thermoplastic rubber insulating material is permanently
molded to the core and coil assembly on the CMV, resulting in a compact unit with excellent mechanical, thermal, and dielectric characteristics.
The CMV and CMV Hi-Temp transformers are supplied with large compression-type secondary terminals, a short circuit device, and a clear rectangular snap-on cover suitable for locking with a meter seal. This clear plastic cover allows a visual check of connections and is keyed to a short circuit device to ensure proper installation. Terminals can also serve as a post-type connector by looping wire under the screw head.
The CMV and CMV-Hi Temp both have an oval primary opening suited to fit over the secondary spade in padmounted transformers.
Optional bus bar adapters for attachment to the terminal spade, available only on the CMV, are shipped with the tapered bottom current transformer. Either design may be secured to a wall panel or bracket by inserting bolts through any pair of mounting holes in the transformer body. |
