Gas discharge tube arresters (GDTs) are widely used in electrical power systems to protect against lightning and transient surges, and reduce stress on power distribution networks. These surge suppressors have been an integral part of power distribution networks for many decades, helping to keep electrical lines safe and secure from high voltage spikes. The T049246 is a GDT with a number of unique characteristics and properties designed to protect against both lightning strikes and induced surges.

The T049246 is designed to offer a highly effective solution for applications requiring both direct and transient lightning strike protection. It is ideal for use in medium voltage power systems, including those used for powering residential, commercial, industrial, and utility substations and networks. The arrester is designed to provide reliable performance for up to and including 20,000A Short Circuit. The T049246’s unique design and construction offers excellent long-term protection from transient over-voltages caused by direct and indirect lightning strikes.

The working principle of the T049246 is based on the use of a combination of gas filled cells and series arresters. The gas filled cells, which are housed within a cylindrical body, are charged with an inert gas such as argon or xenon. When the external voltage across the GDT exceeds its breakdown level, the cells become ionized and current begins to flow. This current is limited by the series arresters which are connected to each cell. As current flows through the series arresters, the gas is heated up and pressure increases, keeping the voltage across the GDT below its breakdown limit until the over-voltage passes. The arrester is then automatically reset and ready for the next transient.

The T049246 has a unique design which allows it to be used in a variety of applications. It features a corona shield for enhanced behavior in high interference environments, and its low profile allows for easy installation and minimal maintenance. The T049246 also has a dust and water resistant design, making it suitable for use in harsh outdoor environments. In addition, the T049246 is constructed from high-grade materials to ensure it can withstand extreme temperature and humidity conditions.

The T049246 is an advanced GDT with highly reliable performance and superior protection against both lightning and induced surges. The unique design and material construction results in a GDT that is highly efficient, durable, and cost-effective. It is ideal for applications requiring both direct and transient lightning strike protection, and is suitable for use in medium voltage power systems. With its corona shield and dust and water resistant design, the T049246 offers reliable protection for years to come.
