Gas Discharge Tube Arresters (GDT)

Gas Discharge Tube (GDT) arresters are electrical devices used to protect electrical and electronic circuits from voltage surges that could cause damage or disruption to the system. GDTs are also sometimes referred to as surge protective devices (SPD). In an electrical installation, a GDT arrester is typically integrated into the system just before the point of electrical connection, so that any surge of current is immediately diverted away from the system.The GDT arrester works on the principle of insulation breakdown, which involves the sudden jump in electrical energy across an electrical circuit when a high-voltage, alternating current (AC) surge is applied. This surge of energy causes current flow between the two electrodes of the GDT arrester. Since the electrodes are made of metal, the current flow causes metal ions to move from one electrode to the other, creating a temporary closed loop of electrical energy. When the voltage returns to its normal level, the charge is dissipated and the arrester is ready to absorb the next surge of energy.The application of GDT arresters in 2027-15-BLF systems increases the resilience and reliability of the system against power surge caused by lightning strikes, heavy industrial activity, and low-voltage grid fluctuations. These surge protectors are also installed at construction sites or near industrial units, where they act as the primary safety measure for all electrical installations.GDT arresters can be affixed together to form protective barriers along long sections of cable. Each arrester in the chain dissipates any turbulence and reduces resistance along the line, protecting all the connected points from damage or disruption of their power supply. With the addition of GDTs to a system, system operators can be assured that any power surges will be diverted away from the main system, minimizing incidents of damaged or malfunctioning equipment. In the application of GDTs in 2027-15-BLF systems, the surge voltage must be kept within predetermined limits to ensure that the GDT can properly absorb or dissipate the surge and not cause any damage to the system. The surge voltages should not exceed 25kV for SPDs rated at 20kV, and the reactive surge current should not exceed the rated capacitance of the GDT. To achieve the effectiveness of GDTs, they must be connected in a specific manner and configured correctly to match the specific requirements of the system. GDTs are reliable, cost-effective devices that can make a significant contribution to the durability and efficiency of a 2027-15-BLF system. With its simple design and effective application, it is an important part of any modern electrical system.
