Isolation monitoring & earth fault detection
in isolated low voltage DC networks
Application
Automated
- Isolation monitoring
- Fault location
- Identification of faulted pole
- Switch (patented) – increased accuracy and reliability of error evaluation
Reliable error analysis
- Reliable detection by leakage current sensors basen on Hall effect
Display of
- Residual current
- Faulted feeder & polarity
Integration into substation automation system via
- IEC 60870-5-104, IEC 61850
- Passive system without active feeding of external currents at highest response sensitivity
- Automated identification of faulted load circuit and pole: selective and rapid, no stressing of operating equipment through manual on/off switching
- Operable up to 220 VDC
- Single device or integrated – customised solution SPRECON®-ISOSCOUT
- Repeatable manual initiation of measuring at any time
- In accordance with the standards of SPRECON-E-C bay computers (EMC, environmental conditions)
- Automated measuring with reduction of residual current on earth fault occurence
- Passive system, no risk of malfunction of automation systems
