The core and coil assembly is wound and encapsulated in a molded cast resin with 4 ½” window porcelain primary bushing(s) to provide high withstand capabilities. The coil is specially designed
and arranged for 3-phase conductor use to prevent localized saturation and/or nuisance tripping. The high strength porcelain(s) has(have) a semi conductive interior with a pigtail lead to be connected to the primary conductor(s) to equalize the voltage and prevent radio interference and corona. The secondary terminals have ¼”-20 studs with associated hardware located inside a removable terminal box with two (2) 1” NPT conduit hubs.
The BYZ-863 / 865 indoor/outdoor zero-sequence current transformer can be provided in 15,000 and 25,000 volt classes, 110 and 150kV BIL to ground, respectively, and is designed to fi t over a variety of specifi ed insulated primary conductors. Primary current ratios are available from 50:5 to 200:5 at 60 Hertz (Hz) with a Rating Factor of up to 3.0. This dry-type, solid-cast, zero-sequence CT will operate with relay accuracy for ground fault detection applications.
