An instrument transformer for high current and/or high voltage conversion includes a housing and at least an active part, which is electrically insulated by an isolation material. The isolation material includes or is a paste and/or pulp. A method for producing the instrument transformer includes the filling of a housing of the instrument transformer with paste and/or pulp, particularly with paste and/or pulp including paper material and/or cellulose, solved in a solvent, particularly at least one ionic liquid.

The application invention generally deals with a double-pole voltage transformer enclosed in a tight enclosure made in the form of a resin cast comprising a central element integrated with a base and comprising circumferential sheds and two bushings situated above the circumferential sheds on the central element. The central element has the form of a circular cylinder situated with its side wall horizontally on the base plane, and the circumferential sheds are situated around the central element only in the area of the contact between the central element and the base, and above the circumferential sheds there are side elements of the cast forming side sheds, and above the side sheds there is situated a circumferential top shed surrounding a fragment of the side surface of the central element, and the bushings are detachably joined with the central element through projections respectively.

An explosion-proof inductive voltage transformer (IVT) of the type comprising: i) a high voltage section that receives a high voltage current, limits and insulates the high voltage current to be transformed and reduces its electrical stress; and, ii) a voltage transforming section connected to the high voltage section and contained in an insulation body in order to protect the elements of the voltage transforming section and reduce the impact of explosions in case of electrical failure, wherein the voltage transforming section comprises means for reducing the voltage of the high voltage current to a low voltage and electric transmission means that transmit a resulting low voltage current to a low voltage distribution line; wherein the voltage transforming section of the IVT further comprises shock mitigation means comprising at least one hollow section located opposite the high voltage section that, during an electrical failure causing an explosion, direct the gases and shockwave of the explosion towards the hollow section, thereby reducing the damage caused by the explosion to the IV transformer and its surroundings; provides an explosion-proof inductive voltage transformer easy to install and with a low cost manufacture.
