2037-15-B

Gas Discharge Tube Arresters (GDT) are devices made up of two electrodes separated by a gas-filled tube. The tube is connected to a circuit that triggers a spark when the voltage across the two electrodes reaches a predetermined level. When the spark occurs, the voltage across the electrodes rapidly drops to a much lower level and the energy released by the spark dissipates in the form of heat, light, and sound. This process is known as arc-over suppression.

The most common type of GDT is the 2037-15-B. It is used to protect electrical circuits from over-voltage surges that could cause damage. The working principle of this type of GDT is based on the discharge of high voltage current through it when a certain voltage threshold is reached.

The 2037-15-B GDT consists of two electrodes: a cathode and an anode. The cathode is connected to a case that is insulated from the environment and the anode is connected to the electrical circuit to be protected. When a high voltage surge occurs across the two electrodes, the gas filled in the tube conducts current from the anode to the cathode. As the current passes through the electrodes, it ionizes the gas and creates a spark.

Once the spark is created, the current is stopped and the voltage across the electrodes drops rapidly. This action is known as spark gap suppression. The 2037-15-B GDT is configured in such a way that the voltage threshold required to trigger the spark is higher than the normal operating voltage of the circuit it is protecting. This ensures that normal operation of the circuit is not excessively disrupted by the spark.

The 2037-15-B GDT is typically used in power circuits, telecommunications, electronic systems, and other electrical applications. It is a reliable and cost-effective way to protect circuits from damage caused by over-voltage surges. Because this type of GDT is designed to have a high voltage threshold, it is also suitable for use in circuits that are subject to wide variation of voltage levels.

In summary, GDTs such as the 2037-15-B provide effective protection for electrical circuits from surges in voltage by rapidly suppressing the voltage across its two electrodes when a certain threshold is reached. This allows for safe and reliable operation of the circuit while providing protection against damage that could otherwise result from an over-voltage surge.
