RGDAT A-70
Outdoor Directional Fault Passage Indicator
This new integrated digital monitoring and protection device provides high-performances, low cost and easy installation. It is suitable for all MV systems, from 8kV to 36 kV with any neutral maintenance. It can be installed either nearby a substation or on a pole, in stand-alone mode. It complies with Enel DY1059-A70 standard.
Benefits
Monitoring along the MV secondary distribution line.
Possibility of accurate calculation non-measurable quantities on overhead lines (for example, homopolar current).
Features
- Protection of maximum phase current (51), maximum directional (67N) and non-directional (51N) ground current and absence/presence voltage.
- 3 remote signaling relay with configurable logic (NO / NC).
- Automatic adaptation to the network frequency.
- Recognition of intermittent arcs in directional earth fault.
- Chronological event recorder with circular memory.
