Voltage dips (also known as “voltage sags”) are short-duration reductions in voltage magnitude. Their duration is typically between a few cycles of the power-system frequency and a few seconds. The interest in voltage dips is mainly due to their impact on end-user equipment. Industrial processes may malfunction or shut down due to a voltage dip resulting in significant financial losses.
Voltage dips are due to short-duration increases in current magnitude, whereas voltage dips due to short circuits and earth faults are of most concern for customers.

Developing economic well-being and preserving a healthy environment are not opposed forces but do, on the contrary, have a primary relationship and require a similar way of thinking: maximizing the efficiency of a product over its life cycle will minimize its total financial cost as well as the total environmental impact over its life cycle.
The case studies bellow were developped to substantiate this Life-Cycle-Thinking by delivering high level messages supporting decision making on the sustainable energy arena.

Switching to energy efficient motor driven systems can save Europe up to 202 billion kWh in electricity consumption, equivalent to a reduction of €10 billion per year in operating costs for industry.
It would also create the following additional benefits:

Since the end of the 1990s the European Copper Institute [ECI] has been concerned about the impact experienced by commerce and industry of the changing nature of the energy demands organisations face as a result of equipment technological advances, the increasing need o build in resilience into their electrical power installations and the presumed mounting costs of not taking either adequate preventative or reactive action to accommodate the changes.

On the January 23, 2008 the European Commission agreed on a far-reaching package of proposals that will deliver the European Council's commitments to fight climate change and promote RE. With the publication of this Climate Action Plan and its several targets, the EU wants to show global leadership in this area.
This report provides an overview of the Kyoto-targets and the objectives of energy from RES in final energy consumption in 2020.

The worldwide electricity savings potential of switching to high efficiency transformers is estimated to be 200 TWh. This savings potential is not only technically advantageous, but also brings economic and environmental benefits. Taking the full life cycle cost into account, selecting high efficiency transformers is often an economically sound investment decision despite their higher purchase price.

The Transmission System Operator (TSO) is responsible for a stable and secure exploitation of the electricity grid in its control zone. This is mainly achieved by contracting power generators delivering ancillary services in addition to their main commercial product, active power. Electricity from Renewable Energy Sources (RES-e) is today generally exempted from the participation in ancillary services. However, the increasing share integration of variable RES-e with a limited predictability has an impact on the demand and supply structure of these services.
