Measuring Harmonics With Inductive Voltage Transformers in Presence of Subharmonics [PDF]
IEEE Transactions on Instrumentation and Measurement, 2021 The measurement of harmonics is one of the key tasks in modern power systems, performed basically for power quality assessment, verification of planning levels compliance, immunity and compatibility purposes, and so on. Especially at medium voltage (MV) and high voltage (HV) levels, harmonics are always measured through voltage and current transformers
