UHF-impulsgeneratoren voor gevoeligheidscontroles op GIS en transformatoren
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 voltage output from its nominal value is less than 30 mV + 0.03 × u, with 'u' being the displayed value.
Additionally, Power Diagnostix offers a cost-effective factory calibration, if the formal traceability is not required. The calibrator is re-adjusted, if necessary, and outfitted with a new battery.
