Gas Discharge Tube Arresters (GDT) are commonly used in electrical power systems to protect equipment from power surges due to lightning strikes or switching effects. T049056 is a two-electrode discharge device that is widely used in these types of installations. This article discusses the application field and working principle of the T049056.

Application Field

The T049056 is used to protect sensitive electrical and electronic equipment from power surges. It finds various applications in over current, over voltage protection, and lightning protection. It is commonly used for the Primary Surge Arrester of power supply lines and the Secondary Surge Arrester for communication lines, to protect electrical and electronic equipment from lightning and other power disturbances.

Working Principle

The T049056 is a two-electrode device with a metal oxide resistive layer between the electrodes. When the device is exposed to an overvoltage, it breaks down, allowing current to flow between the electrodes. This current dissipates the energy of the overvoltage through the resistive layer, thereby protecting sensitive electrical and electronic equipment from power surges. The device is designed to reset itself when the voltage subsides, allowing it to be used repeatedly.

To further protect sensitive equipment, the T049465 is designed to operate in both AC and DC circuits. The device can be easily integrated with a surge protector relay to ensure that the arrester will cut off power in the event of an over voltage or a short circuit. This ensures that damage to sensitive equipment is avoided.

The T049056 also features a low operating energy requirement, which reduces energy costs. The device has a high dielectric strength which makes it suitable for protection against high power surges, and a fast reaction time to ensure that the device kicks into action as soon as a power surge occurs.

Conclusion

In conclusion, it can be seen that the T049056 is a versatile two-electrode discharge device which is suitable for a wide range of applications in the field of power surge protection. The device features a metal oxide resistive layer, a fast reaction time, low operating energy requirements and a high dielectric strength. It is capable of operating in both AC and DC circuits and can be easily integrated with a surge protector relay to ensure that equipment is protected against power surges. Therefore, the T049056 is an ideal choice when looking for an effective and reliable surge protection solution.
