Gas Discharge Tube Arresters (GDT)

Gas discharge tube arresters (GDT) are an important component in any electrical installation. Used to protect against lighting, it is an important piece of equipment for any home, business, or industrial complex. The 2051-20-SM-RPLF gas discharge tube arrester is a specifically designed model used to protect against high energy late stage breakdowns associated with power line lightning events.

In general, a GDT arrester works by absorbing some of the energy from a lightning strike and dissipating it as heat. When a lightning bolt strikes a power line, the voltage rise creates a current pulse that travels along the power line. The GDT arrester will intercept this current and divert it away from sensitive devices and equipment, thus avoiding damage. This process is known as “electrically shortening the pulse”, or “electrically shunning”.

The 2051-20-SM-RPLF arrester is designed to detect and limit lightning surges and maintain a consistent voltage on the system. The arrester has an integrated voltage regulator, which is designed to protect sensitive electronic devices and components from an over-voltage condition. The voltage regulator monitors the voltage level of the system, and will essentially shut off power when the voltage rises to a certain level. This helps protect the system from damage.

The arrester is also protected against arcing as it is filled with pressurized SF6 gas; which is a non-flammable gas used for electrical insulation purposes. The gas helps reduce the chances of electrical arcing and ensures the safe operation of the arrester. The arrester also features an ignition barrier, which helps protect it against anything that may cause ignition or arcing from outside the device.

Installation of the 2051-20-SM-RPLF arrester is relatively simple. It is a three-phase device, meaning there are three legs that must be connected and wired together to the terminals of the arrester. Once the connections are made, the arrester will need to be connected to the ground for proper operation. A qualified electrician should complete the installation process.

Gas discharge tube arresters are a critical piece of equipment for any electrical installation. They are designed to protect sensitive electrical components and devices from any lightning surges or voltage spikes. The 2051-20-SM-RPLF arrester in particular is designed to detect and limit lightning surges while maintaining a consistent voltage on the system, using an integrated voltage regulator and a non-flammable gas for insulation.
