Measurement of Electric Field Intensity nearby High Voltage Power Stations

Abstract

In the area beyond each high voltage overhead line or around any high voltage power equipment, integrated inside power stations or operating alone, high values of the electric field intensity (and/or magnetic field induction) accidentally occur. Certain preventive safety measures, both for the environment, as well as for the human personnel, are mandatory. An objective and fair assessment of the electric field intensity around all these facilities is mandatory, before considering any new design features or limiting the operational exposure. This paper shows some measurements of the electric field intensity, performed at the Fantanele 220kV/110kV/20kV Power Station, located in Central Transylvania, Romania. This power station is belonging to the National Romanian Power Grid Operator, TRANSELECTRICA S.A. Our case study is also filled with some electric field measurements, added to describe the electromagnetic field parameters. Data collected will be also used for the refurbishment of some existing power facilities in Romania and for a dedicated digital map of this potentially high-risk power objectives.
