Risk of voltage surges EXPOSURE TO OVERVOLTAGES: DAMAGE AND COSTS NOT ALL PROTECTION DEVICES PROTECT. CHOOSING WELL IS YOUR RESPONSIBILITY Electrical and electronic equipment is indispensable in the daily activities of today’s businesses and individuals. Such devices are connected to the electricity grid, often exchanging data and signals through communication lines and are usually sensitive to disturbances. These interconnecting networks provide a propagation path for overvoltages. The various players in the chain of sale need to ensure that protection devices comply with the product standards,...

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...

Imax Maximum discharge current Peak current in 8/20 js waveform which the protection device can withstand. In Nominal current Peak current in 8/20 js waveform the protection device can withstand at least 20 times. Up Voltage protection level Maximum residual voltage between the terminals of the protection device during the application of a peak current equal to the nominal current (In). Uc Maximum continuous operating voltage Maximum effective voltage that can be applied permanently to the terminals...

Protection system of coordinated stages: Type 1, 2 and 3 SPDs exceed 10 m. The optimal system of protection is the 3-STEP approach, in which successive stages are combined in the performance of high discharge capacity devices and devices with an optimal voltage protection level (low). This is addressed by the definition of “Types” or “Classes” of SPDs according to the type of transient pulses to which each protected zone in the installation is subject to. The SPDs of a surge protection system must be able to withstand the discharged current and provide a Ures level (residual voltage) lower than...

Grounding systems All national codes on the generation, transmission and distribution of electricity require grounding of all the elements of the installation. This ground connection ensures a sufficiently low impedance path for protection devices to protect people and equipment, and to prevent hazardous step and touch voltages. As we will see, there are several systems for making this ground connection, depending on the interconnection between the installation components. • ndividual ground connection at the consumer level, separated from the transformer. I Without distributed ground conductor...

Power frequency overvoltage protection EN 50550 standard for POP POWER FREQUENCY OVERVOLTAGE Power frequency overvoltages are voltage increases of hundreds of volts, caused by phase imbalances and lasting for an indefinite period. They are usually caused by breakage of the neutral, leading to a reduced service life in the affected equipment, or to their immediate destruction and even fires. The use of these protectors is essential in areas where fluctuations occur in the mains voltage values. U(V) EN 50550 “Power frequency overvoltage protective devices for household and similar applications...
