The Swedish Neutral Automatic Tuning Device continuously monitors the network and tunes the Arc Suppression Coil to the correct value in order to reduce capacitive earth fault currents to a minimum.
Features
- Fast and accurate tuning using the Swedish Neutral Locus Measurement
- Robust performance also during harsh weather conditions with floating neutral displacement –
keeps the ASC tuned when the risk for earth fault is the greatest
- Tunes all types of Arc Suppression Coils
- User friendly handling through HMI and terminal software
- Supplies additional network information (e.g. damping, dissymmetry, mismatch)
- Earth fault alarm with detection of high impedance earth faults
- Control of Neutral Earthing Resistor
- Supports all standard protocols
Options
- Monitoring of harmonic levels for power quality measurements and trend analysis
- U0-Injector for symmetrical networks
