A Gas Discharge Tube Arresters (GDT) is a special type of electrical protection device used in power distribution systems to protect vulnerable electrical equipment from surges and lightning strikes. The GTCS28-900M-R10-2 is an example of a GDT that is widely used in high voltage power systems.

Application Field

The GTCS28-900M-R10-2 is specially designed to protect power systems from lightning strikes, high voltage spikes, and induced transient voltage surges. It can be used in a variety of power systems including rural power distribution lines, urban power distribution lines, industrial power networks, power grids, and DC electrical systems. Due to its small size, it can also be used in a variety of places that require compact protection devices such as railways, airports, and military installations.

Working Principle

The GTCS28-900M-R10-2 is an air-filled spark gap type arrester. It is constructed of two electrodes which are separated by a gap filled with an inert gas. The gap serves as an insulator between the two electrodes and is designed to act as a conductor of electrical current when a certain voltage level is exceeded.

When the GTCS28-900M-R10-2 is exposed to a surge or spike in voltage, it acts as a voltage limiter. The two electrodes are composed of special materials that are designed to be conductive at different voltage levels. The first electrode is conductive at a lower voltage level and the second electrode at a higher voltage level. The gap between the two electrodes is designed to be conductive at a voltage level between the two. This mechanism prevents excessive transient voltages from reaching the protected equipment.

When the voltage level is exceeded, the gap between the two electrodes starts to conduct electrons, limiting the voltage to a safe level. The energy from the excess voltage is dissipated as heat and converted into harmless light. This process is known as “electro-optical” effect. When the voltage level returns to normal, the GTCS28-900M-R10-2 returns to its original state and is ready for the next surge.

Conclusion

The GTCS28-900M-R10-2 is a reliable and efficient protection device for protecting sensitive electrical equipment from power surges, lightning strikes, and induced voltage transients. Due to its small size and wide variety of applications, it is a widely used GDT protector. It works by limiting the voltage to a safe level when triggered by a power surge. In addition, the “electro-optical” effect enables it to dissipate the excess energy and keeps the protected equipment safe from damage.
