In high-voltage electric power systems current-limiting devices are applied to limit a fault current levels, among those current-limiting reactors are extensively applied. In the comprehensive design a particular attention is paid to winding design. Generally, winding is performed using a few parallel wires (branches). The transition between horizontal rows is based on a specific algorithm referred...
At present current-limiting reactors are widely used in order to limit levels of fault currents in electrical networks. Reactor being an element of power system must be able to operate reliably under nominal and fault conditions. Main attention in the paper is focused on calculation method of reactor, operating under nominal condition. A comprehensive approach to calculation of a design of dry type...
Suspension insulator string is widely used as insulator structures in high voltage overhead power lines. Power frequency voltage of feed line is distributed along string elements in unequal amounts due to parasitic capacities (on ground and wire). Grading rings arrangement close to current-conducting elements is one of the most effective ways for voltage grading. The results of investigation of voltage...
