Inverters are themselves sources of interference. To address this interference effectively, the solution is to implement a proper grounding. The purpose of grounding is to eliminate this noise (induced electric field) – if it can't be eliminated, it will wander around, of course leading to malfunctions.
Insufficient cross-sectional area of the power line, especially the grounding wire, which cannot effectively discharge induced electricity.
The entire grounding wire is live, not only failing to exclude but also reversing into phase.
C Line used as neutral causing electrical cabinet leakage
Covering layer damage on the power line caused short circuit and leakage of electricity.
The motor insulation has been damaged, resulting in a ground short circuit.
2. Wiring errors, such as misconnecting PE and N, leading to leakage occurrences.
3. False alarms caused by strong interference from the surrounding environment.
4. The ground wire is not properly connected, or the ground resistance is insufficient.
