SUMMARY

The discussion centers on the standards governing the combination of Low Voltage (LV) and Medium/High Voltage (MV/HV) grounding networks. Participants highlight that these systems are typically managed separately due to the risks associated with faults in one system affecting the other. The conversation references various standards, including IEEE and IEC, but emphasizes the lack of compelling reasons to merge these grounding networks due to safety concerns.

PREREQUISITES
  • Understanding of grounding systems in electrical engineering
  • Familiarity with IEEE and IEC standards
  • Knowledge of Low Voltage (LV) and Medium/High Voltage (MV/HV) systems
  • Awareness of electrical fault implications on grounding networks
NEXT STEPS
  • Research IEEE standards related to grounding, specifically IEEE 142
  • Explore IEC 60364 for grounding requirements in LV installations
  • Investigate the implications of grounding network faults on system safety
  • Examine case studies on LV and MV/HV grounding network separation
USEFUL FOR

Electrical engineers, safety compliance officers, and professionals involved in the design and maintenance of grounding systems will benefit from this discussion.

On which standard IEEE / IEC BS EN / NEC...we can find recommendation on combining Grounding Networks of LV and MV/HV together?
 
In general they are handled separately, there are EE ( PEs) that specialize in grounding. I can not think of any good reason to combine them since a fault on ether system will then have V imposed on the other.
