Description
Systron PowerShield® transformer compact shields
 Compact shields over two 630kVA transformers
|
|
With the Systron PowerShield® transformer compact shielding magnetic fields of Transformers are limited. The compact Shield was developed in cooperation with EWZ Zurich so the installation limit value, AGW, of transformers in accordance with the regulation on non-ionising radiation, NISV, can be met. The compact shield was therefore developed for transformers with different performance and dimensions and is available in different dimensions and shielding factors for transformers up to 1600 kVA. The shielding effect was checked by Electrosuisse. These measurements were performed with currents from 150A to 1900A. The measurement curves show that the AGW in rooms above the transformer station, in transformer stations with the usual room heights, are respected perfectly.
