The perfect supplement to arc suppression devices: freely adjustable project planning and parameterisation software

The AEToolbox works on a project basis and impresses with its range of functions and the versatility that the program offers.

All control, measurement and recording tasks

„around the arc suppression coil“

Our freely programmable arc suppression coil regulators are used in medium and high-voltage networks to regulate continuous, variable-under-load arc suppression coils (Petersen coils, also known as P-coils or E-coils). In addition, they can handle all other control, measurement and regulation tasks having to do with arc suppression coils.

The classic regulation process, i.e. searching for the resonance curve across the range of travel of the coil, can no longer successfully adjust the arc suppression coil in certain network situations.
We have developed this current injection for the increasingly frequent cases where the zero-sequence voltage is highly disturbed or subject to extreme influences or where networks are highly symmetrical. The current injection creates a signal that is fed into the network via the auxiliary power winding of the arc suppression coil. From the network reaction, the combined REG-DP(A) and current injection are able to calculate a resonance curve despite the low or highly variable zero-sequence voltage.
