HV Earthing & Testing

We specialize in the design, installation, and testing of high-voltage earthing systems for substations, industrial facilities, and utility networks. Proper earthing is critical to protect personnel, equipment, and infrastructure from electrical faults, lightning strikes, and transient overvoltages. Our solutions ensure low impedance paths to ground, minimizing risk and enhancing system stability.

Our testing services include insulation resistance, earth loop impedance, step and touch voltage analysis, soil resistivity profiling, and fault diagnostics. We use calibrated equipment and follow IEC and SANS standards to verify system integrity and compliance. Whether commissioning a new installation or auditing an existing one, we deliver accurate, actionable reports and recommendations.

We also offer partial discharge testing, tan delta analysis, and cable fault location for HV systems. Our technicians are trained in safe handling of high-voltage environments and provide full documentation for regulatory and insurance purposes. Trust us to safeguard your assets and ensure uninterrupted power delivery through expert earthing and testing services.
