Gas Discharge Tube Arresters (GDTs) are electronic devices that are designed to protect the electrical systems and power lines from damage due to lightning and other forms of electrostatic transients. One type of Arrester is the GTCR38-351M-P20 which has an application field as well as a working principle.

The GTCR38-351M-P20 is a three phase, medium voltage, gas filled tube. It is used in air insulated industrial power systems, in coastal industries, and in open areas that experience frequent lightning storms. The arrester is designed to withstand up to 20kV and is equipped with a special resistor to limit the current flow during a surge. The arrester has a long wear life due to its use of a high quality gas which is less vulnerable to corrosion. The gas filled tube also has a self-healing property, meaning that the arrester can self-repair any internal damage caused by a lightning strike.

The GTCR38-351M-P20 operates based on the principle that an electric current can be cutoff at a certain voltage level. The device works by containing an insulating medium, typically gas or oil, and then a set of electrodes which create a small amount of electrical breakdown. When a surge of current enters the system, it causes these electrodes to discharge the current, allowing the system to be protected and the voltage to return to its normal level. This ensures that any further current entering the system is not of a danger level.

The GTCR38-351M-P20 is highly durable due to its use of high quality gas and electrodes. It is also designed to be easy to install, making it ideal for a wide range of applications. The arrester is also treated to resist corrosion and has a self-healing property. These features make the GTCR38-351M-P20 a reliable and effective gas-filled tube arrester.

In summary, the GTCR38-351M-P20 is a gas-filled tube arrester that has a number of beneficial properties. It is designed to be highly durable due to its use of high quality gas and electrodes, as well as its self-healing properties. The arrester is also easy to install, making it ideal for use in a wide range of environments. The GTCR38-351M-P20 works based on the principle that an electric current can be cutoff at a certain voltage level, allowing the system to be protected and the voltage to return to its normal level.
