Gas Discharge Tube Arresters (GDTs) are an important component of any lighting protection system, as they protect systems from the damaging effects of high voltage surges. A 2017-35-A-RPLF GDT is a robust member of the GDT family with its ability to absorb and dissipate extremely high voltages. The primary functionality of this device is to protect sensitive electrical systems from the destructive effects of lightning strikes.

This 2017-35-A-RPLF GDT is designed to have a metal oxide varistor (MOV) on the top of the device. The MOV acts as a resistor against surges of current up to a certain voltage threshold. When this threshold is exceeded, the MOV will begin to conduct electricity and thus divert the surge away from the protected equipment and harmlessly ground it. This process of diverting electricity is known as surge current suppression.

This surge current suppression is a two-stage process. During the first stage, the MOV swiftly changes its electrical resistance to ensure that the electrical surge does not exceed a certain voltage threshold. Once the voltage threshold has been exceeded, the second stage involves the MOV pushing the current through its external connections and into the ground, thus providing additional protection.

The 2017-35-A-RPLF GDT is also designed with an internal pressure sensitive switch, a gas-filled tube, and an externally mounted spark gap. The internal pressure switch is used to detect when an electrical surge has occurred and will trigger the gas-filled tube and the external spark gap to switch on. The spark gap completes the surge suppression process by dramatically reducing the energy of the surge and providing a pathway through which the surge can travel harmlessly to the ground.

The combination of MOV, pressure switch, gas-filled tube, and external spark gap work together to provide protection for downstream equipment. When the MOV senses a surge, it immediately reduces its resistance, allowing the current to flow into the pressure switch. The pressure switch then triggers the gas-filled tube and external spark gap to switch on. The gas-filled tube rapidly extinguishes the arc created by the spark gap, preventing any further increase in voltage. Finally, the spark gap provides a path for the surge current to travel to the ground, thus eliminating the danger of the surge.

The 2017-35-A-RPLF GDT is a highly reliable means of protecting electrical systems from destructive surges. Its internal components are designed to act quickly and precisely, allowing the current to be discharged safely and preventing any harm to downstream systems. As such, it is an essential component of any electrical protection system.
