Interconnection / Mains Decoupling

During mains failures, DER (Distributed Energy Resources) should stay operated and connected to the grid to support decreasing mains voltage, by feeding reactive power. Woodward has developed various Intelligent Electronic Devices, which are in compliance with international grid requirements (Grid Codes), to avoid electrical or mechanical damage to the DER in these cases.

The following product lines offer the right Interconnection / Mains Decoupling products to you.

HIGHPROTEC LINE

The new HighPROTEC line is the latest generation of complete protection for medium-voltage power systems. Learn more about HighPROTEC Interconnection / Mains Decoupling devices:
