UHF impulse generators for Sensitivity Checks on GIS and Transformers
Special signal sources are available for GIS and transformer measurements using UHF, such as the CAL2A: 0.5/1/2/5/10/20/50 pC, rise time max. 200 ps, and f3dB min. 1.5 GHz.
Three other models are available with voltage output, the CAL2B: 2/5/10/20/30/40/50 V, CAL2C: 1/2/5/7/10/12/15/17/20 V, and CAL2D: 5/7.5/1015/20/30/40; Z = 50 Ω, rise time max. 200 ps, tF = 100 ns.
The rise time of the calibrators CAL2B/500, CAL2C/500, and CAL2D/500 is typically 550 ps.
Power Diagnostix delivers UHF impulse generators of the CAL2 series with a fully traceable DAkkS calibration. This calibration certificate guarantees that the deviation of the charge output from its nominal value is less than 0.2 pC + 0.02 × q or with the voltage output calibrators (e. g. CAL2B) 0.005 × umess, with 'q' and 'u' beeing the displayed value.
