Descriptions
The Capacitive Voltage Probe (CVP) is designed for measuring asymmetrical disturbances on cables with
capacitive coupling principle. It gives the opportunity to do the measuring without disconnection of the
tested cable (“in-situ”) and it avoids the infl uence of the transmission. Main parameter of the CVP is the
coupling factor, measured in a calibration system with 50 Ω impedance. The capacitive voltage probe is
specifi ed in chapter 5.2.2 and Annex G of CISPR 16-1-2. -
