Type 2 arrester for voltages up to 1000 V
Combines two contrast: High system voltage and low voltage protection level
The undesired tripping of a surge protective device (SPD) in case of voltage peaks up to 2,200 Vpeak used to be a problem especially in wind turbines.
DEHNguard DG SE H 1000 VA comprises a varistor connected in series with a gas discharge tube which prevents undesired tripping of the SPD. This type 2 arrester is therefore ideally suited for use in wind turbines – particularly for protecting double fed induction (DFI) generators.
