Low Voltage Surge Arrester (SPD) Selection and Its Importance in Elevators
6 December 2023
Busbar-Mounted Low Voltage Surge Protective Devices
17 December 2023Intelligent Transportation Systems (ITS) contain many components required for the operation of local intersections, control of signals, and control of ramp meters. Reliability is essential for the safety of drivers and pedestrian crossings. With increasing demand, more equipment is being added to the control cabinets of intelligent transportation systems. However, more equipment means an increasing number of failures. A possible power outage may be triggered by transient events affecting sensitive components inside the cabinet. As a result of a power outage, drivers and pedestrian crossings are put at risk. If these sensitive electronic components remain vulnerable to sudden surge impulses and lightning strikes, the sustainability of the system is jeopardized. These systems, located in open areas, may be damaged by direct lightning strikes or by strikes occurring in the surrounding area.

Raycap AG Surge Protective Devices Should Be Used for Sensitive Electronic Systems
Intelligent transportation systems (ITS) equipment uses sensitive technology that must be protected from the harmful effects of lightning strikes and other line disturbances. Raycap has been manufacturing Surge Protective Devices surge arresters for many years to protect equipment vulnerable to conductive surges. Raycap is a global leader offering a wide range of protective products and components specifically designed for traffic applications. Surge Protective Devices are specially designed to ensure that the system continues to operate without being affected by lightning strikes. SPDs are designed to respond to any overvoltage occurring in the system (for example, voltage caused by lightning or switching events). As soon as a surge is detected, the SPD is activated and begins to operate. It captures, absorbs, and safely diverts the electrical surge, preventing damage or destruction of your equipment. In addition, the SPD stops the surge from spreading throughout the system. SPDs easily prevent your ITS equipment from being destroyed by surges. By performing a risk analysis on your specific ITS system, you can determine the level of protection required to maintain optimal, safe functionality and prevent costly repairs or equipment replacement.

Risk analysis is based on factors such as the size of the installation, its location, and the configuration of your ITS system, and can be carried out quickly by an expert. This is a small step that can have a major impact on the overall effectiveness of your ITS system!
Raycap PROTEC T1LH TYPE 1+2 1P+N series, Raycap SLH communication line and Raydat NET6 POE data line protections are the most ideal solutions for preventing possible surges.
Surge Protective Devices (SPDs) for Traffic Remote Monitoring
Traffic signalization systems used at intersections, traffic remote monitoring devices, and other ITS equipment are sensitive to lightning strikes and therefore require protection. Traffic signalization systems are traffic control systems that include traffic signals, camera systems, and other components. To ensure the operational continuity of the traffic signalization system, this equipment must be protected against lightning strikes. Therefore, Surge Protective Devices (SPDs) are used in traffic control cabinets.

Surge Protective Devices (SPDs) for AC Networks
There are many different types of Surge Protective Devices (SPDs) available for AC networks. In accordance with IEC standards, there are types designed as Type 1 for high exposure areas, Type 2 for regular exposure areas, and Type 3 for terminal protection. AC power LV SURGE ARRESTERS generally use pluggable features to facilitate maintenance operations. DC power networks may be disrupted due to lightning strikes. For this purpose, Raycap offers a range of SPDs. SPDs with multiple DC voltage and surge discharge capacities are available. DC power SPDs use pluggable features to facilitate maintenance operations. DIN rail mounting is possible.
Data lines are extremely sensitive to lightning strikes. SPDs on data lines are strongly recommended to ensure the highest level of security for intelligent transportation systems. Raycap’s product range can offer solutions for all data lines and signal networks. The SPD is suitable for DIN rail mounting and can be extremely compact when there are many inputs/outputs requiring protection.

Raycap offers a wide range of SPDs for HF coaxial lines. They are used to protect equipment connected to radio systems and video coaxial cables. They are available in main coaxial connector versions and are connected in series with the lines and bonded to the grounding network. SPDs with bandwidths up to 6 GHz are available. When LAN is used and communication is carried out over copper lines, the risk of lightning-related damage is high. Special SPDs should be used for both data transmission lines and PoE surge protection. Raycap has designed a range of SPDs for Ethernet line or PoE surge protection. Surge protectors are equipped with RJ45 connectors for easy installation and are available up to category 6 cabling and 10Gbit Ethernet. They are suitable for indoor and outdoor applications.
Surge Protective Devices (SPDs) for Load Stations
When LAN is used and communication is carried out over copper lines, the risk of damage from lightning strikes is high. In this case, 19” rack-format multi-port SPDs should be used for Ethernet line or PoE surge protection at the central hub location. 19” rack surge protectors are equipped with RJ45 connectors for easy installation and are available up to category 6 cabling and 10Gbit Ethernet. The panels contain 12 to 32 surge-protected ports. When video signals are used for inspection, SPDs are required on the lines. Raycap offers a wide range of coaxial line surge protectors that are directly connected to the cable. These SPDs are designed to be compatible with all connector types and bandwidths. Analog video inspection cameras should be protected against lightning strikes due to their high exposure. Load control systems can be damaged by lightning strikes, and failures can lead to equipment destruction and production downtime.

Intelligent transportation systems include many critical components such as traffic signalization, signage, and ramp meter control. To ensure and maintain the reliability of these systems, it is important to use Surge Protective Devices (SPDs). SPDs protect the system against lightning strikes and other line disturbances. This allows the system to operate continuously and keeps drivers and pedestrian crossings safe. SPDs are available for different types of connection points such as AC networks, DC networks, data lines, coaxial lines, and Ethernet lines. To select the appropriate SPD for your intelligent transportation system, it is important to conduct a professional risk analysis. This analysis can be based on factors such as system size, location, and configuration. Surge Protective Devices (SPDs) are critical to the safety and performance of ITS systems and therefore must be selected correctly.
