The present invention refers to HV apparatus, in particular a HV dry current transformer, insulated with an insulating gel, or a voltage transformer, insulated with an insulating gel. The dry HV current transformer comprises at least two electrically conductive elements i.e. a head transformer cover, a head housing base, a core casing and a primary conductor. In the dry HV current transformer at least one of the electrically conductive elements has a coating made of solid insulating material separating the surface of the conductive elements from the insulating gel and adapted for limiting the electron emission from the conductive elements into the insulating gel. The voltage transformer comprises a bottom external housing, a bottom support flange, a core. In the voltage transformer at least one of the electrically conductive elements has a coating made of solid insulating material separating the surface of the conductive elements from the insulating gel and adapted for limiting the electron emission from the conductive elements into the insulating gel.

A high-voltage device includes a housing and at least one subassembly which is electrically insulated from the housing. The at least one subassembly is spaced from the housing and mechanically connected to the housing. At least one ceramic spacer element is disposed between the housing and the at least one subassembly. A method of using the high-voltage device includes transferring heat, which is produced at connection elements of the at least one subassembly which is electrically insulated from the housing, from the subassembly through the at least one ceramic spacer element to the housing and emitting the heat from the housing to the environment.

The present disclosure is a system and method for measuring both load current and residual current within an electronic component. The electronic component includes a first toroidal core for measuring load current and a second toroidal core for measuring residual current, all enclosed within a housing. The system facilitates the measurement of load current and residual current in a small form factor and may be configured to replace legacy electronic components that measure only load current.
