Transient Surge Protection

I. Introduction to Transient Surges

What is a transient surge ? A transient surge is a phenomenon where high voltage spikes travel through conductive materials like wires or electrical circuits.

Sources of transient surges: These high voltage spikes can originate from events such as:

• Lightning strikes between clouds or within a cloud.
• Lightning strikes on structures or lightning rods on the ground.
• Lightning strikes on exposed electrical signal conduits.
• Lightning strikes on the ground or water.
• Switching activities (on/off) of high-power motor machines can also cause electrical surges on connected lines.

.

Characteristics of transient surges: These electrical spikes typically have very high intensity and voltage, characterized by specific waveforms that travel very quickly along conductors, instantly affecting connected electrical and electronic devices.

Harmful effects of transient surges: They cause damage and reduce the lifespan of electrical devices and can pose dangers to humans. These harmful effects include damaging electronic circuits, causing fires or explosions, and disrupting the operation of machinery and equipment systems.

II. Introduction to Transient Surge Protection

What is transient surge protection ? Transient surge protection involves using specialized measures and devices to mitigate the indirect effects of lightning strikes, aiming to protect connected electrical and electronic devices from damage.

Role of transient surge protection: Alongside lightning rods that protect structures, transient surge protection (TSP) plays a crucial role in protecting internal electrical and electronic devices. TSP is an essential part of a comprehensive protection system, helping to ensure safety, extend the lifespan of electronic devices, reduce damage risks, and maintain the continuous operation of machinery and equipment systems.

III. Methods of Transient Surge Protection

Preventive measures

• Disconnecting: Disconnect unnecessary electrical devices during storms to avoid damage from high voltage spikes.
• Limiting the use of conductive materials: Using non-conductive materials like fiber optics to reduce risks.
• Utilizing charge dispersion technology: Installing external surge protection systems using dispersion rods.

Active protection measures

Installing specialized surge protection devices (SPD): Using specialized devices to block, redirect, and neutralize electrical spikes.

IV. Transient Surge Protection Using Specialized Devices

General principle: Using transient surge protection devices installed on connection lines such as power supply or signal transmission lines to block and neutralize high voltage spikes, bringing them down to a safe level for the protected electrical devices behind them.

Types of transient surge protection based on connection lines

• AC power source surge protection: Using suitable surge protection devices installed on the electrical distribution system's lines to block and neutralize electrical spikes before they enter the electrical devices that need protection.
• DC power source surge protection: Using DC surge protectors installed on direct current electrical lines to block and neutralize transient electrical spikes, ensuring the safety of devices using DC power sources.
• Data and telecommunications line surge protection: Using Data surge protectors installed directly on signal transmission lines to block electrical spikes, protecting telecommunications equipment and data processing devices like computers, servers, network devices, sensors, etc.

V. Conclusion

Transient surge protection is a critical component in comprehensive lightning protection, helping to protect electronic devices and electrical systems from the effects of lightning. Choosing and installing the right transient surge protection devices ensures safety, extends the lifespan of devices, and maintains the continuous operation of the system.

To achieve optimal protection, it is necessary to combine preventive and active measures, selecting the best surge protection solutions to build a suitable transient surge protection system for each structure, delivering significant benefits in protecting assets and maintaining the continuous operation of the system.
