Filter resistor
PRINCIPLE
Modern electrical equipment requires a stable voltage supply with low levels of harmonic distortion. However, electrical installations often generate interference causing disturbance to electrical networks. This leads to various problems such as:
Overheating
Malfunctioning of control or remote monitoring systems
High currents in the different phases or neutral lines
Resonance problems
As a result it is necessary to have harmonic filters. These are basically composed of capacitors and inductors. The addition of a resistor allows:
Easier filter tuning at installation,
Widening of the pass band,
Greater tolerance of temperature changes in the components.
APPLICATIONS
HDVC conversion stations (LCC & VSC)
Transmission voltage regulation
Power quality and transfer increase
Reactive power control
Voltage stabilization(Wind farm)
Dynamic voltage support (Railway)
Arc furnances, rolling mills (Metal)
Winders and crushers (Mining Industries)
Compressors, pumps and drill
Electrical propulsion and diesel systems

Resistor for railway applications
On electrical locomotives braking is achieved by both mechanical brakes (drums & disks) and electrical brakes, which are usually high performance rheostat type resistors. Gridex resistors equip the French high speed train, the TGV, which requires a powerful braking system, and other types of transport such as local trains and tramswhich have frequent braking cycles.

Demisting resistor / mirror
StopVapor is an entertaining decoration which will undocked user's variety of bathroom articles over change and aspect. It has been created according the European safety regulations (EN 60335) and the CE regulation mark. To install this, The user just needs to leave 1 cm between the wall and the mirror to allow the cable to pass through. It is very accessible to set up because it is a self-adhesive heating foil that should be connected at the back of the mirror in the desired position. It prevents the mirror from steaming-up, so the user can see reflection instantly and entirely.
