CAL2 Series

Impulse Generators

Power Diagnostix UHF impulse generators and PD calibrators enjoy all the advantages of 25 years' experience in calibration services. The broad range of easy-to-use and robust units for many different applications ensures reliable PD measurements compliant to international standards, such as IEC 60270 and CISPR 18-2.

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 CAL2B with voltage output: 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.

DAkks calibration mark

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.

The standard impulse generators of Power Diagnostix' CAL2 series are listed in the table below, along with their ranges and key features.
