Overview of Overvoltage Protection: Overvoltages are voltage increases exceeding 10% of the nominal voltage for an indefinite period, potentially causing equipment overheating, reduced product lifespan, fires, destruction of equipment, and service interruptions. Protection devices are essential in areas with voltage fluctuations.

Types of Overvoltages:

Power Frequency Overvoltages (TOV): Also known as permanent overvoltages.
Transient Overvoltages: Short-duration voltage spikes caused by events like lightning strikes or switching operations.

Protection Devices and Their Operation: Protection devices act as voltage-controlled switches installed between active conductors and ground. They remain high-impedance under normal voltage but switch to low-impedance during overvoltages, diverting excess voltage to the ground.

Selection and Classification of Protectors: Protectors are classified by discharge capacity and voltage protection level into Classes I, II, and III, each tested with specific waveforms to simulate different overvoltage scenarios. Selection depends on network topology, nominal voltage, and exposure to lightning or transient overvoltages.

Installation and Coordination: Effective protection often requires a coordinated system of multiple protection stages, ensuring high discharge capacity and low residual voltage. Proper installation involves maintaining specific distances between devices and using appropriate cabling to minimize voltage impact.

Standards and Parameters: Protection devices are evaluated based on parameters like maximum residual voltage (Up), nominal current (In), maximum discharge current (Imax), and maximum continuous operating voltage (Uc). Standards such as IEC 61643-1 and UL 1449 3rd Ed. provide guidelines for classification and testing.

Visual and Remote Indication: Devices may include visual indicators for local end-of-life signaling and remote indication capabilities for monitoring the status of protection devices.

Conclusion: Proper selection, installation, and coordination of overvoltage protection devices are crucial for safeguarding electrical systems against the damaging effects of overvoltages.

What are Overvoltages? Theoretical concepts What are overvoltages? Transient overvoltages (SPD) Transient overvoltages are 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...

Theoretical concepts Power frequency overvoltages (POP)** Besides the phenomenon of transient overvoltages, which may affect any type of conductor, electric transmission lines can transmit another type of overvoltage, known as power frequency overvoltages. These are considered to be any voltage increase above 10% of the effective nominal value for an indefinite period. POP overvoltages are caused by problems in the electricity distribution network or, more commonly, by bad connections or breakage of the neutral conductor. Most electric distribution systems in the world use a neutral conductor,...

Theoretical concepts General operation of a protector A transient overvoltage protection device acts as a voltage controlled switch and is installed between the active conductors and ground in parallel with the equipment to be protected. When the supply voltage is lower than its activation voltage, the protector acts as a high-impedance element so that no current flows through it. By contrast, when the supply voltage is higher than the activation voltage, the protector acts as an element with an impedance close to zero, leading the overvoltage to earth and preventing it from affecting the receivers.

Theoretical concepts Selection of Up based on the category of equipment to be protected The protection device should be selected so that the voltage protection level (Up) is compatible with (lower than) the value of the maximum voltage withstood by the equipment to be protected (Ue). For the purposes of standardising design criteria and selection of protection devices, IEC standard 60364-4-443 classifies equipment into four categories, based on the impulse voltage they are capable of withstanding. N/A: Not Applicable NOTE 1: Uo is the phase to neutral voltage of the low voltage supply NOTE 2:...
