VARSET : Energy Efficiency
Give Oxygen to your electrical network
 Power Factor Correction and Filtering means energy savings : it allows
to use your transformer (installation) at its maximum efficiency and to
stop the system losses :

 Power Factor Correction and Filtering decreases voltage drops, avoids
the overload of the network, and allows the diminution of harmonics so
that you will not have to overrate your installation.
 Power Factor Correction means cost savings : it allows to erase your
reactive power invoice if the utilities of your country is applying penalties

 Example of an European country where there are penalties :
 the rule is cos(φ) > 0,9
 For example, if cos(φ) = 0,7 the company will be charged for
reactive power. The cost savings, thanks to a power factor
correction installation, will be :

VARSET :
Give peace of mind to the End Users
 Number of hot points has been reduced, decrease of the heating in
the banks --> Mastering the thermal withstand
 Less losses = less heating = more power in the same cubicle than
before :
 600 kvar / A3 cubicle for the Classic range (450 kvar in the
past)
 450 kvar / A3 cubicle for the Comfort range (405 kvar in the
past)
 300 kvar / A3 cubicle for the Harmony range (250kvar in the
past)

VARSET :
Give peace of mind to End Users
 Life duration of VARPACT is 15 years (130 000 hours)
 Each capacitor bank is tested at 100% in the manufacturing plant
(following IEC standards).
 Decrease of hot points inside the banks, and decrease of the temperature
inside cubicles compare to Rectimat2.
 Connection bus bars have a Icc withstand 35 and 50 kA (new IEC
standard)

VARSET :
Give peace of mind to End Users
 No maintenance during the first 5 years
 After 5 years, we advise you to measure the capacitance value of
VARSET to keep the maximum efficiency for your installation.
 No corrosion thanks to the plastic envelop of the VARPLUS²
capacitors.
 Safety of the operator during the maintenance operation thanks to
the internal discharge resistor.
 Protection against direct contacts during the maintenance thanks
to the protection plate.

VARSET :
Give safety to the End Users
 Using of the new VARPLUS² technology :
 A new production line fully automated especially designed for
VARPLUS²
Automatic controls at each step of the production
Robots for high quality
 Mechanical resistance of the enclosure has multiplied by 2
 High quality protection system :
VARPACT is the one to use this technology, allowing to prevent
100% of the eventual defaults.

VARSET :
Give safety to End Users
•
Against internal defaults (with a low current),
thanks to the overpressure system
Dielectric losses its self healing
properties
Gas pressure increases slightly
and reaches the below.
The below rise
The metallic disc short circuits the
terminals across the fuse.
The faulty capacitor is out of
service.
CEF - Marketing - 2006
•
Against external defaults (with high current),
thanks to the HRC fuse
 The fuse protects against
high current faults > I fuse
 It operates for high current
short time faults

VARSET :
Give involvement to the environment
 VARPLUS² used inside VARSET is ROHS compliant (Restriction Of
Hazardous Substances). It means that VARPLUS² doesn’t contain any
substances with concentrations exceeding the limits fixed by the ROHS
Organism.
 Involvement to the environment (ISO 14001) :
 VARSET is a dry technology : free of liquids.

VARSET :
Give Oxygen to your electrical network
 VARSET will give to your electrical installation, its maximum
energy efficiency :
> To erase expense on reactive power
> Higher transmission capacities for effective power
> Environment involvement thanks to a lower electrical
consumption
> Improvement of power quality
> Reducing the operating costs
 The installation of VARSET capacitors banks means :
> a static system, don’t need maintenance
> Life duration of 15 years
> Fast Return on Investment (average time 2 years)
