Compensation d’énergie réactive
Un Cos phi = 1 ? On s’y engage et on vous le garantit même
Elexpert offers a complete range of fixed, automatic contactor or fast thyristor capacitor banks, standard or equipped with anti-harmonic chokes.
The choice of tuning frequencies for the anti-harmonic chokes is quite large and adapted to the customer’s needs: 135Hz, 170Hz, 189Hz, 215Hz. Other frequencies can also be considered, depending on the customer’s needs.
Filtrage des harmoniques
protéger vos installations et optimiser la durée de vie de vos équipements
Harmonics have a negative effect on the life of machines and equipment, household appliances, cables and power lines, motors or transformers. The neutral conductor and the protective conductor can also be heavily overloaded by harmonic currents.
Harmonics are created by so-called “non-linear” loads, such as electronic speed controllers, inverters, LED lighting, welding machines, etc., which distort the sinusoidal electric current.
We offer several filtering solutions that suppress the most dangerous harmonic frequencies.
Protection contre les coupures de courant dans l’industrie
Protégez vos installations industrielles contre les creux de tension et les interruptions
A voltage dip (also known as a “voltage sag” or “voltage crash”) is a brief decrease in the RMS line voltage to between 10 and 90% of the nominal voltage. The duration of a dip is 1/2 cycle to 1 minute according to the IEEE1159 standard. Common sources of dips are the starting of large induction motors and failures in transmission and distribution lines.
Elexpert offers several solutions to protect your industrial installations against power outages
Protection contre les coupures de courant dans le Bâtiment/
protéger vos installations et optimiser la durée de vie de vos équipements
Since its creation in 2007,
ELEXPERT
has made zero defect electrical energy control a business in its own right. Among our first applications were solutions for the protection of IT and telecom infrastructures, including server rooms, data centers, audiovisual content production studios, banks, etc.
Protection contre la foudre
ELEXPERT, c'est la garantie d’une gestion globale et efficace du risque foudre
Elexpert offers several exterior lightning protection systems are possible. They differ according to the capture devices and the principle of lightning current flow to the ground.
All these protection systems are equal. The choice of the type of protection depends on the nature and the activity of the site to be protected, as well as on the objectives of the customer (budget, conformity to a particular standard, etc.)
Protection contre les surtensions
Nous protégeons vos installations contre leur principal ennemi
There are different types of overvoltages: oscillatory transients (switching overvoltages, ferro-resonance phenomena, …), impulse transients (lightning strikes, switching of static converters, …), temporary overvoltages (induced by uncorrected faults, neutral cut-off, …) or long term overvoltages (problems in load adjusters, underloading of lines, internal faults in transformers, …).
The solutions we deploy can be as rich and varied as the surge phenomena.
