THE 'SURGE PROTECTOR' SOLUTION In order to limit surges generated by lightning to an acceptable level for equipment and installations, , the most efficient solution is setting up a protection device against these surges, called « SPD » (Surge Protective Devices) on AC power or communication networks of the installation to protect. The CITEL Company proposes a complete range of surge protectors adapted to all the different types of networks and all configurations of installations AC Surge Protectors CITEL DS AC power surge protection devices are designed to meet all your surge protection needs for any low voltage installation. These DIN rail mounted surge protectors are easy to install in any standardized distribution pane or control cabinets. They are equipped with a thermal disconnection device and provide real-time fault indicators thus allowing complete operational safety. These surge protectors are available with several protection circuits to comply with even the most demanding installations and standards compliance requirements. CITEL offers a line of surge protectors for the single and three phase AC networks connected to sensitive equipment. These products, are available in various formats: Hard-wired units single-phase or Hard-wired units and combiner box for US market. Photovoltaic Surge Protectors The photovoltaic grid-connected low voltage power lines may be subject to overvoltages on different networks: AC, DC or communication network. Depending on the type of networks, the presence of lightning rod or primary surge protectors existing, CITEL offers a complete range of solutions to protect the AC part of the PV system. LED systems Surge Protectors LED street lighting is now widely used, nevertheless this attractive technology has an important weakness: its sensitivity to transient voltages created by lightning or by power switch operations on AC network.. CITEL offers a full range of surge protectors designed to be installed at different points on the lighting network such as streetlights, the base of poles and street cabinets. Many versions have been proposed to meet the various existing configurations: surge protection devices are available in different isolation classes (Class 1, Class 2) and connection type (wire or screw terminal), as well DIN rail mounting version. Telecom and Data Line Surge Protectors These subassemblies can be easily used by the installer and the home user. They are designed to protect PBX’s (Private Branch Exchange) and all the information and electronic equipment either connected to the phone system or to the Local Area Network (LAN). In 1982, the private phone market offered society its first important opportunity of diversification. The demand, linked to the implementation of digital telecom centrals and terminals more and more fragile, is growing fast. This evolution requires the design of very effective protection systems adapted to all networks, actual and future. Coaxial Surge Protectors To complete the range of surge protection, CITEL offers a diversified line of coaxial surge protection to protect coaxial feeds and antennas. With the wide range of mobile equipments available (GSM, PCN, UMTS, BLR...), coaxial protectors are becoming more and more important and continue to evolve towards new technology such as Quarter Waves. Wind Turbine Surge Protectors Wind turbines are generally located at exposed areas for better wind conditions, onshore wind turbines usually locate at prominent terrain like mountains region and offshore locate at coastwise, by the effect of location and the height of structure, wind turbines have higher annual estimated number of lightning strikes according to lightning location system. All types of lightning flashes generate lightning electromagnetic impulses (LEMP) on the connecting cables between the equipment, and the damage is mostly caused by insufficient impulse withstand voltage level of equipment components. LEMP is the main threat leads to malfunction and failure for electrical and electronic systems, now the most efficient measures to reduce loss towards LEMP is using coordinated SPD protection consists of a set of SPDs properly selected. CITEL has designed a complete range of Type 1 / Type 2 / Telecom-Data surge protectors for Wind turbine applications that are compliant with the IEC 61400-24:2019 et IEC 62305 standards.
