MS5000

Check mesh network health, antenna position, and battery status. Use USB interface for diagnostics. 

Verify fault detection thresholds and ensure phase synchronisation is active. Inrush blocking setting may delay response, so adjust in configuration. 

Ensure the line current exceeds the required minimum (1.5A for SU / 3A–5A for GS). Check for proper clamp contact and clean conductor surface if oxidised or insulated. Confirm correct clamp accessory is used (e.g., MS5000-AC-IN for insulated conductors). 

Check mesh network connection strength and ensure synchronisation is active. Review radio frequency environment - interference or improper antenna positioning may impact communication. 

Verify that mesh topology includes intermediate nodes if distances exceed single-hop range. High-gain antennas can improve range, so reposition or replace if signal is weak. Check if cellular or Ethernet uplink is functioning properly. 

Waveforms capture current and voltage changes in high resolution. Use phase-to-ground and surge indicators to confirm fault type. Harmonic distortion and zero-sequence data highlight grid imbalance or power quality issues. 

Real and reactive power, along with power factor and harmonics (up to the 5th presented), give a complete picture of power quality. Alarms help isolate overloads, faults, or low battery events. 

Consistent phase angle shifts can indicate load imbalances or wiring issues. Zero-sequence values help identify asymmetrical faults or grounding problems, especially in compensated or SWER systems. 

The presence of higher-order harmonics (especially 3rd and 5th) may suggest non-linear loads or equipment malfunction. Compare harmonic signatures across phases to pinpoint the source. 

Use the synchronised, timestamped data to correlate detected anomalies with grid events such as switching operations, lightning strikes, or substation faults. This enables precise root-cause analysis.
