Current transformers produce a small current proportional to the primary load current, for measurement, metering or protection purposes. In this instance the high-voltage primary is insulated from the low-voltage secondary winding by SF6 gas.
I trasformatori di corrente producono una corrente proporzionale alla corrente di carico primaria, per scopi di misura, misurazione o protezione. In questo caso, il primario ad alta tensione è isolato dall'avvolgimento secondario BT mediante gas SF6.
