Product Description

Specialized in the design and construction of industrial transformers

*• Through-put rating up to 150 MVAr

In electric arc furnaces, which use long arcs and high values of secondary voltage, it is often helpful to introduce an additional reactor
with the purpose of:

• Arc stability and power regulation
• Optimisation electrodes consumption
• Limitation of current during smelting process
• Reduction of flicker on the feeding network.

The reactors are series connected with the furnace transformers and have some regulation taps (for the reactance regulation) operated
with either an onload tap changer (OLTC), for maximum flexibility, or with a de-energized tap changer (DETC). 

The reactor can be assembled:

• Inside the main transformer tank
• Entirely separated from the transformer
• Located next to the transformer (On Board Reactor).

In the OBR (On Board Reactor) solution, the reactor and the transformer are  linked by a removable cable duct.

• Extends equipment lifecycle due to reduced unstable arc furnace currents
• High mechanical strength withstands elevated forces caused by elevated switching currents
• Tap adjustment is possible
• Inductance of the reactor is frequently variable and requires large adjustment steps
• Conservative temperature rise ensures extended service life
• Surface treatment protects against UV radiation and pollution
• Environmentally friendly
• Maintenance-free design
