eDCAP-601A Universal Protection and Control Device

Tsinghua Unisplendour eDCAP-601A Universal Protection and Control Device

1 Overview
The eDCAP-601A Universal Protection and Control Device is suitable for the protection and control of lines (incoming or outgoing lines) and certain outgoing equipment (such as outgoing transformers or grounding transformers) in systems with ungrounded, low-resistance grounded, or arc suppression coil grounded configurations at voltage levels below 110kV.
The eDCAP-601A Universal Protection and Control Device supports the IEC61850 station control layer communication protocol and enables the publishing and subscribing of substation events via the GOOSE network.
