Gas Discharge Tube Arresters (GDT)

Gas Discharge Tube Arresters (GDT) are devices used to protect electrical equipment from the effects of lightning, power surges, and other electrical disturbances. GDTs are typically used in applications such as power lines, telecommunications equipment, and in industrial and aerospace environments. GDTs are generally composed of a gas-filled tube that is filled with an inert gas or mixture of gases, such as air or nitrogen. The gas is ionized by the applied voltage to create a conductive path for the current to travel.

In a GDT, an applied voltage causes the gas to break down and form a conductive path for current to flow. The voltage at which the gas breaks down and conducts current is typically referred to as the breakdown voltage (VBD) of the GDT. The current that passes through the GDT is normally limited by an internal resistance that is made up of the ionized gas and electrodes inside the tube. The amount of current that can pass through the GDT is typically denoted by a characteristic, such as the maximum discharge current (Imax).

VS350A-B Application Field and Working Principle

The VS350A-B is a series of gas discharge tube arrester, designed and developed by Sanrex Corporation, that has a maximum discharge current of 350 amperes (A) and a breakdown voltage of 1,800 volts (V). This GDT is typically used in applications such as power lines, telecommunications equipment, and in industrial and aerospace environments. The device is also rated to withstand a peak surge current of up to 2,500A.

The working principle of the VS350A-B GDT is based on the principle of a gas-filled tube. When a high voltage is applied, the internal gas becomes ionized causing a current to flow through the tube. This current is limited by a series of electrodes inside the tube which are designed to withstand large amount of current. The internal resistance of the GDT limits the current to the maximum discharge current of the device.

The VS350A-B is also designed to self-heal after each incident of surge. This is done by cooling down the ionized gas and allowing it to return to its original non-conductive state. This helps the device to resist multiple surges so that the life span of the device is extended.

In addition, the VS350A-B GDT comes with a reverse polarity protection design which prevents the device from getting damaged in case of a reverse power supply. This feature ensures that the device is highly reliable and durable for use in various applications.

The VS350A-B GDT is a cost-effective solutions for protecting electrical equipment from the hazards of lightning, power surges, and other electrical disturbances. It is designed to offer superior protection by limiting the amount of current, preventing reverse polarity, and self-healing after each surge. This makes the device highly reliable and durable for use in various industrial and aerospace applications.
