The core and coil assembly is wound and tape wrapped with various window sizes from 6” up to 44”. The CT has an internally shielded winding for 10kA and above rated units to minimize the effects of stray fl ux from adjacent current carrying conductors.
The CT is mounted to the non-magnetic insulating board using high strength straps and silicone adhesive to provide excellent mechanical strength to withstand the high vibration application on generators. The secondary terminals are #10-32 screws located inside an aluminum terminal box with two (2) 1” NPT conduit hubs. The unit is moisture resistant and can withstand direct water spray equivalent to 1” of rain per hour for two hours and remain dielectrically sound.
The GCT-848 indoor/outdoor, board-mounted generator current transformer is a 600 volt, 10kV BIL rated unit and designed to fit over a variety of specifi ed bushing sizes. The insulation of the bushing provides the dielectric protection for the CT. Primary current ratios are available up to 50,000:5 (as well as up to 25,000:1) at 50 and/or 60 Hertz (Hz) with a typical Rating Factor of 1.0 @ 55°C. This unit is ideal for new installations or for quick replacement/retrofi t on older generators. This Mylar or polyester tape-wrapped, board-mounted CT will operate with high accuracy for metering and/or relay applications.
