The GESINNE system is a smart voltage regulator that stabilises the electrical supply’s voltage for an installation, optimising both for proper load function and decreasing consumption, since it is more efficient. Both optimum supply voltage regulation and balancing between phases through independent control for each one of them lead to huge advantages and great energy savings.
Technical issue. Electric network supply
There are mainly two voltage systems cohabiting in Spain: B2 (220/380 V) and B3 (230/400 V).
There is a single infrastructure that supplies clients with very different needs, which leads to voltage fluctuations along the entire line. Electrical networks are several kilometres long and are linear. They must meet a legal minimum voltage for the last supply point on the network. Surcharges normally occur at the points closest to the power generation sources, and undervoltages with the last users on the line.
By Royal Decree, distributors have a +7% tolerance or margin over the nominal voltage they must supply (220V and 230V, RD 1955/2000).
Electronic equipment are designed to work within this interval, but they will not consume the same or have the same life cycle.
According to Fortescue’s Theorem, a voltage unbalance at 5% between phases reduces performance in motors and three-phase switchgear and motors by 25%.
Moreover, when the same intensities are not circulating through the three phases in a three-phase system, this unbalance creates overheating, bearing wear and a reduced life cycle for the equipment.
On the other hand, due to the effect of Joule heating, when the current passes through wires, thermal losses directly proportionate to it occur, which leads to greater electricity consumption.
EFFECTIVE RMS VALUE
STANDARD ELECTRICAL EQUIPMENT
Equipment operates at optimum working voltage, leading to improved efficiency and savings on active energy.
Reduced reactive consumption: this is a decrease in apparent power, which has a positive effect on efficiency.
Oversized installation: reduced energy consumption in installations where the effective work obtained is greater than necessary.
