Testing & Measurement
Protection is proven by measurement. LPES field engineers carry out earth-pit resistance tests (fall-of-potential and clamp-on), soil-resistivity surveys by the Wenner four-pin method, continuity and bonding tests, earth-fault loop impedance, step and touch voltage and grid resistance measurement to IEEE 81, SPD testing, insulation resistance and thermography — with calibrated instruments and a signed test report for every point.
