Most issues around power quality are the result of incorrectly configured electrical systems. Keep an eye out for short circuits between neutrals and your grounding network, which often create disturbances in power quality, causing the devices connected to your power system to malfunction.
This problem occurs when part of the return current in the neutral conductor flows through grounding conduit and conductive parts of the building, and back to the service entrance. This current, called an earth leakage current, can generate a range of issues, including:
⦁ Creating noise in the electrical system that often enters devices’ grounding circuits, causing them to malfunction.
⦁ Strong, stray magnetic fields that may negatively affect the adjacent electrical equipment in your building.
⦁ Major voltage differences between separate grounding points, which could be extremely dangerous.
It is extremely important to protect the people in your building against possible electric shock. Electric shock can occur as a result of either direct contact with ‘live’ conductors, and via indirect contact (via metal enclosures during short circuit conditions).
Inadequate earth leakage protection exposes the people working in your business to the risk of electric shock, which poses a range of risks relating to severe injuries and even death.
