IET Science, Measurement &Technology, Volume 20, Issue 1, January/December 2026.A series resistive‐capacitive divider for harmonic voltage measurement of gas‐insulated switchgear was studied. It can step down the voltage while amplifying the proportion of harmonics in the total sensed voltage, thereby increasing the significant figure for the measurement and enabling the accurate measurement of high‐order, low‐amplitude harmonics.
