Guidance for engineers and site managers.
Practical, no-cost reading on keeping earthing, lightning and surge protection compliant — and proving it stays that way between test dates.
What really happens to your earthing between annual tests — and why a valid certificate can sit on a system that is no longer compliant.
Read →Why lightning and surge claims increasingly turn on proving your protection was working at the moment of loss — not just certified last year.
Read →Solar PV and battery storage (BESS) add lightning-attractive DC systems to sites whose earthing, lightning and surge protection were never designed for them.
Read →A compliance reading is only as good as its provenance — the calibration, method, competence and unbroken record behind it. A raw number is not the same as assured evidence.
Read →What the revised grounding-measurement guide changes for South African engineers — transient (surge) impedance, and the factors that quietly distort an earth reading.
Read →How continuity alerts turn a silent failure into an immediate response.
Read →A practical checklist for keeping evidence audit-ready year round.
