Gas Discharge Tube Arresters (GDT) are essential components of any electrical installation because they protect equipment from overvoltage and power surge currents due to lightning strikes or other accidental events. The GTCR38-501M-R10 is a reliable and efficient GDT that is commercially available. This article will discuss the application field and working principle of the GTCR38-501M-R10.

The GTCR38-501M-R10 is a type II trans-gap gas tube arrester that can be used for various power protection purposes. Its application field includes trees, power poles, substations, or house roofs. It is suitable for both overhead power lines and underground cables. It is designed to provide protection against all types of phenomena caused by overvoltages and power surges.

The GTCR38-501M-R10 has excellent performance characteristics and can withstand both low and high energy impulses. It has an excellent surge current withstand capability, up to 30KA per impulse. The arrester clamps peak voltage to less than 1000V maximum. The arrester also has an excellent protection ratio, which is 50% above 8KV in low frequency and 25% above 6KV in high frequency.

The GTCR38-501M-R10 has an impressive resistance to weathering, making it suitable for outdoor installations. It can withstand temperatures of up to 70°C and withstand exposure to ultraviolet light. Additionally, the GTCR38-501M-R10 has an operating life of more than 90 years.

Now, let’s move on to the working principle of the GTCR38-501M-R10. The gas discharge tube arrester works on the principle of a breakdown gap between two metallic electrodes. A small gap is designed between the two electrodes to dissipate or clamps any excessive voltage or current when subjected to lightning or transient pulses. When a surge voltage of sufficient magnitude appears across the electrodes,ionization of the air within the gap occurs and a spark passes through by creating a conductive path. This results in a rapid reduction in the current flow, providing the desired protection.

The inherent protection is provided by the construction of the GTCR38-501M-R10’s design. The GTCR38-501M-R10 has two electrodes made from stainless steel or beryllium copper, which are separated by a gap which contains a gas-filled discharge tube. The gas-filled discharge tube within the gap restricts the flow of current and reduces the peak voltage.

The gas-filled discharge tube contains a mixture of Argon, Nitrogen, and an encounter of hydrocarbon and inert gases with pressure of typically between 1 and 2 atmospheres. This mixture of gases is also responsible for the breakdown of the gap, which is essential for overvoltage protection.

The GTCR38-501M-R10 is easy to install and maintain. It is designed to provide effective and inexpensive protection against overvoltage and power surge. It is ideal for use in harsh environments, as it can safely and reliably protect against transients and high voltage. Furthermore, its high quality components and construction ensure a long lifetime, and its low cost makes it an appealing choice in the field of gas discharge tube arresters.
