Capacitive Voltage Probe (CVP) can measure the common-mode disturbance voltages without contact to the cable. However, it is necessary to obtain the correction factor for each cable. Although the measurement method by two CVPs was developed to measure the voltage without the correction, this has the disadvantage that this needs two CVP, this need the signal generator, and etc. This report proposes the measuring method without cable correction by changing the loading capacitance of CVP. In the investigation, a cable was replaced with a copper rod, and the correction coefficient was measured by the gain-phase analyzer. The results indicated that the deviation of the measuring voltages was within 3dB form 150 kHz to 30 MHz, the measurement value slightly changes depend on the loading capacitance value, and the deviation increases when the frequency is greater than 10 MHz. The disturbances from telecommunications equipment were measured to confirm the validity of the method, the results indicated that the measurement results were almost the same as the results using impedance stabilization network (ISN). |
