A properly designed and maintained earthing system is the foundation of electrical safety. Earth integrity testing verifies that the earthing network provides a low-impedance fault current return path, limits touch and step potentials to safe levels, and ensures protective devices operate reliably during an earth fault.
Service Scope
Earth Resistance Measurement
- ›Fall-of-potential (three-terminal) method for individual earth electrodes and earth mats
- ›Stakeless / clamp-on earth resistance testing for multi-point earthing networks
- ›Selective testing of individual earth electrodes within a combined earth grid
Soil Resistivity Survey
- ›Wenner four-pin method across the site footprint
- ›Soil resistivity profile at different electrode spacings to determine soil layer structure
- ›Data used for earth grid design verification or remediation planning
Earth Grid Integrity Verification
- ›Continuity testing of buried earth conductors and bonding connections
- ›Step and touch potential measurement at critical locations
- ›Comparison against IEC 60364, IS 3043, and IEEE Std 80 limits
Neutral Earthing Resistor (NER) Testing
- ›Resistance and condition check of neutral earthing resistors
- ›High-current injection test for NER performance verification
