The GTCR38-471M-R10 is a type of Gas Discharge Tube Arresters (GDT) designed to protect electrical equipment from transient voltage surges originating either from lightning strikes or from energized power line arcs. Most commonly used in high-voltage switching stations and power distribution networks, the GTCR38-471M-R10 is an example of the latest advances in GDT technology that has been designed to optimize performance and minimize the risk of equipment damage.

The GTCR38-471M-R10 consists of a cylindrical aluminum or steel housing with two electrodes providing a small gap between them. Inside the housing is a gas discharge tube which has an atmosphere of low-pressure gas such as sulfur hexafluoride (SF6) and a series of electrodes that are responsible for conducting the electric current. When a voltage pulse above the normal operating range is applied, the increased electric field causes electrons to break away from the molecules of the gas, creating a plasma discharge from the electrodes. This plasma discharge acts as a source of current, creating an arc that passes through the gap between the electrodes causing them to ionize the gas molecules with electrons, further breaks down any electric field, and eventually extinguishes the arc.

In the event of a lightning strike or other high voltage surge, the GTCR38-471M-R10 will instantly respond and discharge the energy into its own internal discharge circuit. This ensures a safe and reliable protection of the electrical equipment by limiting the surge current to a predetermined level. The GTCR38-471M-R10 is also designed to provide a voltage threshold based protection with a maximum discharge current of 10 A at a nominal surge voltage of 3800V, making it suitable for use in high voltage power distribution networks.

The GTCR38-471M-R10 incorporates the latest advances in GDT technology to ensure reliable operation in high voltage applications and effective protection from transient voltage surges. It offers easy installation and maintenance, enabling users to replace only the failed GDT component as opposed to a complete unit, resulting in lower maintenance costs. In addition, the GTCR38-471M-R10 has a compact and lightweight design that enables users to save valuable space in their installations.

The GTCR38-471M-R10 is capable of withstanding extremely high electrical surges for a long time and effectively preventing damage to the electrical equipment. It is an ideal choice for high voltage applications, and provides reliable protection from transient voltage surges that can cause severe damage to electrical equipment.
