Surge protection
TRANSIENT VOLTAGE SURGES IN LV POWER LINES

Transient overvoltages are voltage surges that can reach tens of kilovolts with a duration of the order of microseconds.Despite their short duration, the high energy content can cause serious problems to equipment connected to the line, from premature aging to destruction, causing disruptions to service and financial loss.This type of surge can have various different causes, including atmospheric lightning directly striking the external protection (lightning rods) on a building or transmission line or the associated induction of electromagnetic fields on metallic conductors. Outdoor and longer lines are the most exposed to these fields, which often receive high levels of induction.
It is also common for non-weather phenomena, such as transformer centre switching or the disconnection of motors or other inductive loads to cause voltage spikes in adjacent lines.

SURGES IN TELECOM AND SIGNALLING NETWORKS
Surges tend to induce currents in all metal conductors; not only are the power lines affected, but so are all cables to a greater or lesser extent, depending on the distance to the focus of the surge.
Although a lower current is induced, the effect produced is equally or more destructive, due to the greater sensitivity of electronic equipment connected to communications lines (telephone, Ethernet, RF, etc.).

IMPORTANCE OF THE GROUND CONNECTION
Overvoltage protectors (SPD) divert excess energy to ground, so limiting the peak voltage to an acceptable value for connected electrical equipment.
A ground connection in adequate condition is, therefore, a key aspect for effective protection against overvoltages. Monitoring ground connection condition guarantees proper operation of surge protection devices.
