Understanding the Varieties of Industrial Surge Protective Devices

 

Industrial surge protective devices (SPDs) are critical in safeguarding electronic equipment and infrastructure from power voltage spikes, which can cause significant damage and downtime. Raycap, a leading provider of surge protection solutions, offers a wide range of SPDs tailored for industrial applications.

 

The Role of Surge Protective Devices

 

Surge protective devices are designed to protect electrical systems from power  overvoltages. These voltage spikes can result from various sources, including lightning strikes, power outages, and the switching of electrical loads. SPDs function by only letting through the amount of energy a protected device can handle. They protect sensitive electronic equipment and ensure operational continuity.

Types of Industrial Surge Protective Devices

1. Metal Oxide Varistors (MOVs):
• Functionality: MOVs are widely used in industrial SPDs due to their ability to absorb and dissipate high-energy transients. They operate by clamping voltage spikes to safe levels, thereby preventing damage to electronic components.
• Advantages: MOVs offer reliable protection and can handle large surge currents. Raycap's Strikesorb technology incorporates large, advanced MOVs in a unique design, providing robust protection with a long operational life.
2. Gas Discharge Tubes (GDTs):
• Functionality: GDTs protect against high-energy transients by ionizing gas within a sealed tube. This process creates a conductive path that diverts the surge to the ground, thereby protecting the connected equipment.
• Advantages: GDTs are highly effective in handling high-energy surges and offer a high level of protection when used in combination with other suppression technologies, such as MOVs.
3. Transient Voltage Suppression (TVS) Diodes:
• Functionality: TVS diodes are semiconductor devices that respond rapidly to transient voltage spikes. They clamp the voltage to a safe level, protecting sensitive electronic circuits.
• Advantages: TVS diodes are known for their fast response time and precise clamping voltage, making them ideal for protecting high-speed data and communication lines in industrial environments.
4. Hybrid Surge Protectors:
• Functionality: Hybrid surge protectors combine different suppression technologies, such as MOV, GDT, Spark Gap and TVS diodes, to provide comprehensive protection.
• Advantages: This combined approach enhances the device's ability to handle various surge conditions, ensuring robust and reliable protection. Raycap's ProTec T1H and T1HS systems are excellent examples of hybrid protectors designed for specific applications.
5. Primary Surge Arresters:
• Functionality: Primary surge arresters are installed at the main entry point of electrical power into an industrial facility. They provide the first line of defense against external surges, such as those caused by lightning strikes.
• Advantages: These arresters are designed to handle the highest levels of energy, ensuring that the majority of the surge is neutralized before it can reach and damage internal equipment.
6. Secondary Surge Arresters:
• Functionality: Secondary surge arresters are used within the facility to protect specific equipment or sections of the electrical system. They provide an additional layer of protection beyond the primary arresters.
• Advantages: By targeting specific points within the electrical system, secondary arresters help to isolate and protect critical components, ensuring that even if a surge penetrates the primary defenses, the damage is minimized.
