Lightning is a high-frequency electrical phenomenon which causes overvoltages on all conductive items, especially on electrical cabling and equipment.Lightning strokes can affect the electrical (and/or electronic) systems of a building in two ways:

Measuring Earthing Value/ How to lower the Ground resistance The Most effective way of lowering earthing resistance is to drive earthing electrodes deeper. Soil is not consistent in its resistivity and can be highly unpredictable.It is critical
