This Application Note discusses the use of active filters to reduce harmonic currents in installations. Active filters work by providing the harmonic current required by the load instead of it being drawn from the supply.
The major advantage of active filters is that they can be distributed around an electrical network in a decentralized manner, which enhances the effect of filtering. They can be programmed to respond to selected or all harmonic frequencies and quickly adapt to changes in load profile.

In this report attention is paid to the laminated covering, replacing the conventional lead sheath with corrugated aluminium or copper sheath in HV cables. Various designs and related pros and cons for both copper and aluminium laminated coverings will be discussed. Finally international experience and observed trends will be listed, resulting in the conclusion that a long term view, in which the beneficial properties of copper play a part, is recommendable.

It’s easy for us to say we support renewable energy. But in practice, what is our willingness-to-pay (WTP) for it?
A key factor in whether a particular country or region is likely to reach its renewable energy objectives – such as the European Union’s goal to achieve a 20% overall share of renewable energy by 2020 – is how willing households are to migrate to its use from conventional energy.Read full article
