Gas Discharge Tube Arresters (GDT) are protection devices that are used to protect electronics from the effects of overvoltage. They are most commonly used in surge protective devices, power distribution infrastructure, and telecommunications systems. GDTs are designed to shunt or short-circuit a high-voltage transient to ground before it can reach the protected equipment or system.
Overview
The GDT is based on a two-electrode gas-filled tube that is constructed of a glass envelope filled with a mixture of inert and semi-inert gases. The two electrodes are connected to each other, and have a spark gap that provides an "ignition" source. When a high-voltage transient is detected, the spark gap is triggered and the device initiates an electrical discharge that is directed away from the protected equipment. This discharge serves to shunt the high-voltage transient to ground.
Advantages
The main advantages of GDTs are their low price, relatively simple construction, high surge capability, and low maintenance requirements. Additionally, GDTs are designed to respond quickly to overvoltage transients, minimizing their effect on any connected equipment. Furthermore, GDTs are highly reliable and require little additional circuitry to function.
2015-SMH-RPLF Application Field and Working Principle
2015-SMH-RPLF is a surge protective device (SPD) that utilizes Gas Discharge Tube (GDT) technology. It is a type of overvoltage protector designed to protect low voltage (LV) circuits from the effects of transient overvoltage. The device works by redirecting transient overvoltage away from the LV installation, creating a system for protection from electrical surges and overvoltage that exceeds the normal operating voltage of the system.
The 2015-SMH-RPLF consists of a series of GDTs connected in parallel, each GDT containing an internal spark gap. When the GDT is subjected to a transient overvoltage, the spark gap initiates an electrical discharge that is directed away from the protected equipment. This discharge effectively shorts the surge to ground, thus dissipating the surge harmlessly away from the LV installation. Street lighting and energy distribution systems are some common examples of applications that utilize this device.
Limitations
Gas Discharge Tube Arresters are subject to several limitations. For example, they are relatively costly compared to other protection devices, and require periodic maintenance and an additional circuit for their proper functioning. Since a surge needs to be present in order for GDTs to respond, they are not effective protection for steady-state overvoltage. GDTs also require additional circuitry to be released and reset after a surge. Additionally, GDTs are subject to aging and need to be replaced after a certain period of time, depending on their application.
Conclusion
Gas Discharge Tube Arresters are an effective and reliable protection device for the protection of vulnerable electronic equipment against transient overvoltage surges. They are relatively cost-effective compared to other protection devices, and require only a minimal amount of additional equipment and maintenance for their function. 2015-SMH-RPLF is a GDT-based SPD designed for LV applications, and is an effective solution for protecting street lighting and energy distribution systems from transient overvoltage.
