Lighting Protection

Lightning strikes can disrupt electrical power systems, damage communication and control systems, and frequently cause loss of life. Protecting these systems from lightning-induced overvoltage is a must for preventing serious lightning related accidents. Such efforts to prevent lightning-induced overvoltage in power systems, communication systems, and control systems is the aim of Lightning Protection.

LSP05GI277PX3316 is an overvoltage protection device that helps protect electrical circuits from lightning strikes or similar transients. This device combines an element, which is based on Thyristor Surge protectors (TSP), and an integrated lightning current arrester. This combination provides protection from both lightning overvoltage and current. The element is responsive to both low-to-high and high-to-low transient events. It reacts to lightning-induced impulses by controlling their peak and duration.

Application Field

The LSP05GI277PX3316 is designed for protecting electrical circuits in various areas such as home appliances, telecom equipment, HVAC systems, HFC infrastructure, and industrial systems. It is also suitable for lightning protection of Ethernet, PoE, VoIP, and fiber optic network systems.

Working Principle

The LSP05GI277PX3316 is designed to be connected in series with the electrical circuit. It has two modes of operation, one for normal operations and the other for protection from lightning-induced electrical surges. The first mode of operation draws a minimum current, while the second mode of operation draws a much higher current. This device is capable of acting as a bidirectional protection device, so it is suitable for both low-to-high and high-to-low transient events.

When the voltage exceeds a certain threshold, the TSP begins conducting. This dissipates energy stored in the circuit, and thus, the voltage peak is controlled. The subsequent current is limited to a safe value and it is connected to the ground via the lightning, current arrester. This lightning current arrester functions by providing a path for the current to flow out of the system safely. It is also designed to handle high-power transients and is capable of dissipating a large amount of energy quickly.

The LSP05GI277PX3316 is also designed with an automatic reset, which will reset the device and restore the electrical circuit to its normal state after a certain amount of time has elapsed. This automatic reset feature is important, as it prevents damage to the circuit by preventing the continuous flow of a high current.

In summary, the LSP05GI277PX3316 is a reliable lightning protection device that utilizes both a Thyristor Surge Protector (TSP) and integrated lightning current arrester for bidirectional protection. It is designed to provide both fast and efficient protection from lightning-induced overvoltage and current, and it is suitable for a wide range of applications such as home appliances, telecom equipment, HVAC systems, HFC infrastructure, and industrial systems. With its fast response time, automatic reset feature, and ability to handle high-power transients, the LSP05GI277PX3316 is an effective solution for protecting a system from lightning-induced events.
