20.1 Introduction
Capacitive and inductive voltage sensors are mainly utilized in low-frequency electric measurements.
In this chapter, the capacitive and inductive measurement with large voltage ranges, from 10

to 10

V,
has been discussed. e associated voltage waveforms can be periodic or impulsive. In periodic wave-
