ELETTROMECCANICA TIRONI's Petersen coils meet the international standards (IEC, IEEE / ANSI, ...) and are built according to the specifications of the customer.
The Petersen coils are single phase and are used for grounding the neutral of the transformer.
Due to the continuous variation of the inductance value obtained by the adjustable core and the regulation obtained by the control unit it is possible to achieve the resonance with the network capacity and continue to supply power even in case of a short circuit bringing almost to zero the interruptions of energy supply.
Petersen coils detail:
- Power up to 20MVA
- Voltage up to 145kV
- Current range adjustment 10% - 100%
