Shunt reactors (BIS ZU 40 MWAR)
Reactor installed in three-phase networks to increase power factor during off-load or reduced load conditions, reducing losses in the transmission lines (capacitive).
Typically it is installed in the wind farms where variation of the load factor is extended.
It has a fixed rating, connecting to the power line all the time (it can be switched on/off depending on the load).

SHORT-CIRCUIT CURRENT LIMITING REACTORS
These are usually large single-phase coils without a solenoid, grouped and connected in three phases
parallel to the line.
Installation requires some precautions, since there is a magnetic field next to the coils.
Therefore, you should especially carefully design the foundation and partition structures.
For a small voltage level, three-phase reactors immersed in mineral oil can be used.
This significantly saves space and allows the installation to be as convenient as possible, since the magnetic field is nearby

PETERSEN COILS
There are single-phase reactors (with or without a magnetic wire) connected between the center of the star and the Earth.
If the resistance value of the Petersen coil can be calculated, then the current of a possible ground fault in the network can
can be significantly reduced in order to avoid immediate decoupling.

PETERSEN PISTON COILS
In terms of system design, they have the same function as the fixed Petersen coils,
but the resistance value is adjustable in a certain range. Therefore, the circuit parameters can be adjusted
based on the circuit and network characteristics, which further reduces the switching current.
Adjustment is carried out by moving the core along the axis inside the coil. Movement is controlled
by an electric motor connected to the corresponding gearbox, which ensures high accuracy and
reliability of the mechanism.
In 2004-2005, the Petersen coils were manufactured by SEA as part of the ENEL protocol (National
the Italian Energy Supply Organization) and have received a corresponding confirmation.
