Substation Earthing Arrangements TRIZ Cases
- Electrolytic Grounding Electrode for Dry and Shallow Soils
A salt-replenished conductive column improves grounding in dry or shallow soils by leaching electrolyte outward for more uniform conductivity.
- Ground Loop Impedance Monitoring via Inductive Signal Coupling
Inductive elements impose and receive signals on a ground loop circuit to measure impedance continuously, eliminating manual site visits for verification.
- Dummy Fuse Gravity Polarizer for Safe Earthing
Gravity moves the polarizer to block incorrect insertion, preventing unsafe grounding.
