| Arc Suppressing Coil sized for neutral currents between 80 Amp. and 600 Amp. by 40 Amp. steps |
|

 |
Main Characteristics : |
|
Arc Suppressing Coil (ASC) is operated by a vacuum switch, which is actioned by a a continual examination system of the network.
Additional equipment :
Auxiliary Service Transformers (TSA) are designed for the low-voltage supply of HV / MV substations. On request, this equipment can be fitted with a Protection and Disconnection function (TPC). In case of damage, the TSA immediately disconnects itself from the network and so preserves the supply delivered by the HV / MV substation.
Frequency Injection Transformers (TIF) are dry-type transformers fitted in the HV / MV substations in the building, which allow the injection of remote control signals of 175 or 188Hz.

Additional Features : |
|
Succeeding a first generation of fixed neutral point coils, this new generation of adjustable Arc Suppressing Coil ensures a continuity of supply and makes faults self-extinguishing (neutral current set for 10 seconds to 600 Amp or 1000 Amp). Much effort is being directed especially towards the globalisation of products and services, which includes electronics (controls), coil equipment and the audit of existing conditions on site.
In order to guarantee an optimum quality of supply, a number of directional-type Fault Detectors has just completed this product range.
