2. High voltage measurement with voltage divider and oscilloscope
The concepts discussed in this section relate directly to the measurement of high-frequency components. The use of an oscilloscope is essential for observing the temporal evolution of quantities as well as voltage values. Since high voltage requires a gearbox and a transmission line, we'll start with a reminder of the basic concepts associated with these components.
2.1 Measurement circuit and properties
The measurement circuit can be represented as shown in figure 9. The voltage to be measured at the foot of the voltage reducer is represented by a voltage source ui and an internal impedance Zi (which may include a matching impedance).
The transmission line is characterized...
