HVDC converter station - Wikipedia· The converter transformers step up the voltage of the AC supply network. Using a star-to-delta or "wye-delta" connection of the transformer windings, the converter can operate with 12 pulses for each cycle in the AC supply, which eliminates numerous harmonic current components.The insulation of the transformer windings must be specially designed to withstand a large DC potential to earth.

How to understand electrical cables, flexes & fuses ... a sharp knife to carefully slit the sheathing down the centre (above the earth core). Peel back the sheathing and cut it off using side cutters, then cut the cores to the length you need. Use wire strippers to remove just enough of the coloured cores' insulation so they extend to the full depth of the terminal, with no wire exposed.

Transformer - Wikipedia transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits.A varying current in any one coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force across any other coils wound around the same core. . Electrical energy can be transferred between ...
