OPTInet has been speciﬁcally designed to meet the ever increasing power quality issues that can be easily found in a wide range of industrial applications.
OPTInet combines the established and consolidated characteristics proper of ORTEA voltage stabilizers with features that enable the achievement of energy saving and power quality improvement. One of the factors that most affect energy saving is given by the fact that electrical appliances are usually designed to operate with an input voltage included in range rather than just one nominal voltage. Nevertheless, supplying a device a voltage higher than the rated one implies higher consumption and decrease of the expected life.
For example, supplying resistive loads 240V instead of 230V implies approximately 10% increase in the power consumption
This situation can be found worldwide due to the fact that several distribution systems are rated for a voltage higher than 400V (United Kingdom, Australia, parts of India, and so on): OPTInet provide with a practical an efﬁcient answer to such issue.
Furthermore, higher supplying voltage might induce problems in magnetic components (possibility of magnetic core saturation).
Other factors such as proximity to power plants or distribution stations and voltage supplied at high level to cover the far end of distribution lines might affect performance of the supplied loads and energy bills.
In order to optimise energy consumption, the ﬁrst step is a load survey performed by a qualiﬁed technician aiming at assessing the existing situation, deciding what steps need to be taken and estimating the potential energy savings. The survey is made necessary by the fact that not all loads are voltage-sensitive.
To sum up, the main parametres that allow for the estimation of the energy saving are:
An accurate analysis shall allow for the best solution in terms of design and rating. In some cases, it could be more sensible and economical to install an optimiser only for speciﬁ types of loads.
OPTInet is speciﬁcally designed to allow the adjustment of the voltage received from the mains and bring it back to the value for which the load has been built.
OPTInet optimises the load performance, thus obtaining lower consumption, energy saving, cost reduction and longer life expectancy.
