In this specific case we’d like to show how we solved the compensation of a big manufacturing company producing copper and aluminium wires.
The electrical installation is composed of two transformers 1250kVA / each, steady connected in parallel and a power centre cabinet for the supply of all the loads. The main loads are protected by MCCB.
Loads are mainly big motors driven by frequency converters for old and new generation drawing machines and other machines needed to manufacture copper and aluminium cables.
The goal was to compensate the reactive energy of the whole installation with a single PFC equipment, in order to gain a cosφ greater than 0.95 at the level of the electrical counter in Medium Voltage side.
