Records You Can See
Grounding is invisible until it fails, so proof matters. A recorded test, with date and result, reassures users far more than a verbal claim. The best grounding is the one you can show was checked by a competent person with the right instrument.
Hold The Standard
The standard is simple: continuous, low-resistance path to earth, verified, not assumed. Any deviation is a fault, not a minor detail. Holding this line is what makes every other safety feature meaningful, because without it the rest is built on a silent, deadly assumption.
Re-verify After Change
Dongshang New Energy re-tests grounding after any site change, because a connection loosened during other work is the classic way a good installation goes bad silently while everyone assumes the original test still counts.
Grounding is the promise that a fault will go somewhere safe. Test it, record it, and re-test after disturbance, and that promise stays honoured; assume it, and the first fault becomes the last safe moment.
