Gas Discharge Tube (GDT) Arresters are devices that protect sensitive electrical equipment from the damaging effects of high voltage transients. Developed in the 1950s, these devices have become a major part of high voltage electrical protection systems around the world. GDTs can be used in almost any situation where power is needed – from consumer electronics to military aircraft – to keep delicate circuitry from experiencing power surges and lightning-induced transients.

The most common type of GDT is the T049147 arrester. These GDTs are designed for use in medium voltage (up to 30 kV), transient protection applications where high performance protection is required. The T049147 GDT can be used in both initiating and follow-up protection systems, and is suitable for use in both indoor and outdoor environments.

The application field and working principle of T049147 GDT are straightforward. The device consists of a high-voltage gas-filled tube with two electrodes at either end and an arc-gap in the middle. When the voltage between the two electrodes reaches a certain pre-set level, the arc-gap breaks down, releasing the stored energy and allowing a very controlled current flow between the two electrodes.

The working principle of the T049147 GDT arrester is based on this breakdown effect. When a surge or transient occurs, the high voltage is quickly transferred through the gas-filled tube and the arrester acts as a spark gap, allowing current to flow between the two electrodes. This current flowing through the GDT will quickly dissipate the energy of the surge or transient, thus protecting the sensitive electrical equipment.

The T049147 GDT can also be used in follow-up protection systems, where a surge arrester is placed downstream of the primary protection, which acts as the first line of protection. The primary protection will limit the voltage rise of surges and transients, thus reducing the stress applied to the GDT downstream. In this way, the two arrester types combined provide a reliable solution for most medium voltage surge protection applications.

The T049147 GDT arrester has many advantages over other types of medium voltage surge protection devices. These include a wide current range, high surge current capacity, low inductance, high energy absorption capability, small size, and low cost. In addition, GDTs have advanced remote monitoring capabilities, allowing them to be monitored and maintained from a distance. The T049147 GDT also has a long operational life and requires minimal maintenance.

Gas discharge tube Arresters are an essential component of any high voltage protection system. Their non-arc ignition design reduces the risk of secondary arcs and associated damages, making them the most reliable type of arrester available. The T049147 GDT Arrester is an ideal choice for applications that require a reliable, high performance surge protection device.
