T049016

Gas Discharge Tube Arresters (GDT) are used extensively in power systems. The T049016 GDT is of particular value in the protection of equipment against lightning surges, surges caused by switching and other electrical transients. It is composed of two electrodes separated by a gas-filled dielectric tube. The most important component of the T049016 is the gas discharge tube, which is filled with an inert gas but can be easily ionized at higher electric field strengths. During operation, the electric field in the gap of the gas discharge tube surpasses the dielectric strength of the gas, thus setting off a spark that effectively “short-circuits” the high voltage transient. The T049016 has a fast response time, allowing it to act quickly enough to protect sensitive equipment from damage resulting from lightning surges or other transients.

The T049016 gas discharge tube arrester has several advantages. First, it is a low noise arrester, with minimal emissions when compared to other arrester designs. Second, it has a high discharge rate for high voltage transients, providing excellent protection. Third, the T049016 has a fast response time, allowing it to act quickly enough to protect sensitive equipment from damage. Finally, the T049016 has a very good dielectric strength, which is a measure of the voltage required to cause sparks to short circuit or disrupt the arrester.

The working principle of the T049016 is based on the phenomenon known as “gas folding”. This process occurs when a voltage is applied to a gas-filled dielectric tube. As the gas is charged, its electrons become attracted to one of the electrodes, creating a gas gap across the tube. As the gas gap increases in size due to the electric field, the dielectric strength of the gas decreases. As the dielectric strength approaches the breakdown voltage of the gap, a spark will occur between the two electrodes, creating an \'all-or-nothing\' response.

The application fields of the T049016 include the protection of electrical equipment from surges caused by lightning, switching and other transients. It is especially well-suited for use in industrial and commercial locations, such as plants or offices where power disturbances are a frequent occurrence. The T049016 can also be used in combination with other arresters, such as surge arresters, to provide a higher level of protection. Further applications of the T049016 include high voltage research laboratories and educational environments.

In summary, the T049016 gas discharge tube arrester is a useful device for the protection of electrical equipment against lightning surges, surges caused by switching and other electrical transients. It has a fast response time, a very good dielectric strength, and a low noise level. It can be used in a variety of applications, including power plants, industrial and commercial locations, high voltage research laboratories, and educational settings. The working principle of the T049016 is based on the phenomenon of gas folding.
