What is "ground potential rise" phenomenon? How it cause damage to electrical and electronic equipment inside and outside the building? Jun 01 , 2026
Ground potential rise is caused by transient high potentials resulting from lightning current entering the ground. When lightning strikes a building's lightning rod or the nearby ground, thousands to hundreds of thousands of amperes of lightning current are discharged through the grounding system. Due to the resistance and inductance of the grounding system, according to U=IR+L·di/dt, the potentia...

How is the Up value determined in an SPD with multiple protection modes (such as L-N, L-PE, N-PE)? What is the important guiding significance of SPD selection Jun 26 , 2026
According to the standard, the declared Up value of a multi-mode SPD is the maximum residual voltage value measured across all its protection modes. For example, for a three-phase SPD, if the residual voltage is 1.5 kV in L-PE mode, 1.8 kV in L-N mode, and 2.0 kV in N-PE mode, then the Up value of this SPD should be specified as 2.0 kV. This means that the protection level provided by this SPD to ...
