General Description
The DCDW is a large window type current transformer designed for use with watt-hour meters and intended for installation around secondary bushings in pad mount transformers. Special designs are available for operating in high temperature environments up to 85° C. The transformer meets all applicable IEEE, ANSI and NEMA standards. A wide variety of accessories and ratings allows for maximum versatility.
Construction
The oval core is wound from high quality grain-oriented silicon steel which has been annealed. The secondary winding is accomplished with heavy enameled copper wire evenly distributed around the core. The core and coil assembly is then completely encapsulated in polyurethane resin inside a molded shell of tough glass reinforced nylon. The tapered lower half of the outer shell allows for a tight triangular fitting when the middle unit is mounted upside down.
Secondary Terminals and Cover
Secondary terminals are tinned bronze compression type with a large 7.5 mm (.29”) diameter cross-hole. A bronze pivoting short circuit device interferes with the proper placement of the clear polycarbonate cover when the shorting device is in the shorted position. The terminal cover is designed to accept a sealing device.
Mounting
The transformer is designed for wall mounting and comes with 2 through holes. Also standard are removable bus bar clips for attaching the transformer to the terminal spades inside the transformer cabinet.
Test Reports
Test reports according to the latest revisions of IEEE C57.13 are stored electronically at time of test and can be sent via email in customer preferred formats at time of shipment.
