Product Description

+++++Arc suppression coils (Petersen coil )
Arc suppression coils are used to compensate for capacitive
currents when ground faults occur on an electrical network.
They are connected to the starpoint of the feeding power
transformer or by a starpoint build by a separate earthing
transformer.
Arc suppression coils are continuously adjustable reactors
covering:
1. Nominal network voltages from 6 kV to 145 kV
2. Rated power from 125 kVA to 30 000 kVA
3.  2 h duty time or continuous operation
The basic requirements conform to the IEC 60076-6
standard.
