Gas Discharge Tube Arresters (GDT)

Gas discharge tube arresters (GDT) are devices used to protect electric equipment from external surges induced by lightning and other electrical phenomenons. They act as a surge protector by diverting the unnecessary current away from the protected equipment. The 2027-60-SM-RP application field and working principle are no different.GDTs are composed of a pair of electrodes in a gas-filled chamber, which together form a source of gain or loss of electrons. When there is no voltage applied to the terminals, the equilibrium point is at an almost neutral potential, where the number of injected and removed electrons remains balanced. When subjected to a voltage, however, the electrons in the anode gain energy and are accelerated towards the cathode, causing the device to become highly charged until it reaches its breakdown voltage. Once the threshold voltage is reached, the discharge occurs, resulting in a spark, and a large current is momentarily allowed to flow between the anode and the cathode. This current is designed to discharge unloaded as quickly as possible, to prevent it from damaging any equipment connected to the GDT. This process is known as clamping or transient voltage suppression (TVS), and helps protect against system-level damage.The 2027-60-SM-RP GDT is based on the 2027-60-SRP design with the addition of a metal-oxide varistor (MOV) to increase the surge-handling capability. The MOV is used to absorb the surge energy, allowing the GDT to operate up to 60kV and suppress surges of up to 10kV. As a result, the 2027-60-SM-RP is able to provide a greater degree of protection from electrical faults and surges.In terms of applications, the 2027-60-SM-RP GDT is well suited for protecting pumps, motors, lighting circuit breakers, and other electric equipment from high-voltage surges caused by lightning, power outages, switching operations, and other stray voltages. The device is also designed for outdoor applications, such as tower lighting, communication systems, security systems, and substations, offering an effective solution for these high-voltage environments.As a note, this GDT should not be used for extended exposure to high voltage, as this can reduce the effectiveness of the device over time due to degradation of the MOV. The device should also not be used in high-temperature environments or in applications where rapid-cycling is required, as this can cause damaging arcing.In conclusion, the 2027-60-SM-RP GDT is a highly effective and reliable surge-protection device designed to protect electric equipment from high-voltage surges and electrical faults. With its MOV, the device is able to absorb the surge energy and handle up to 60kV, making it ideal for outdoor applications such as tower lighting, communication systems, security systems, and substations.
