Perturbation measurements on HV overhead lines using Electric Field Sensors

Contactless voltage sensor for overhead transmission lines

“…There were also other applications utilising the EF sensor in the power quality measurement. In [21,22], the remote method was proposed by using a single EF sensor. This method is only limited to the power quality assessment, which is used for measuring parameters like voltage sequence, voltage level, total harmonic distortion for three-phase voltages.…”
