COMBINED ELECTRONIC TRANSFORMER WITH ORGANIC INSULATION FOR OUTPUT OF OPTICAL SIGNALS Russian patent published in 2009 - IPC H01F38/34 

FIELD: electricity.

SUBSTANCE: in the proposed combined electronic transformer with organic insulation for outputting optical signals, the insulator of a capacitive potential divider with organic insulation is used as the main insulator for complete withstanding of high voltage. An air-core coil is wound on the lead-out of the capacitor armature in the insulator of the capacitive potential divider for measuring current. A low voltage signal is obtained from the capacitor armature, located next to the lead-out of the capacitor armature in the insulator of the capacitive potential divider for measuring voltage. The obtained current or voltage signal is then converted into an optical signal by a converter, which converts an electrical signal to an output optical signal. The air-core coil has a current sensor in form of zero potential and the capacitor has a voltage sensor in form of low potential.

EFFECT: increased reliability.
