Introduction to Gas Discharge Tube Arresters Gas Discharge Tube Arresters (GDTs) consists of high-voltage gas-filled spark plug-like tubes with electrodes connected to a metal body. GDTs have the ability to protect circuits from high-voltage spikes, such as lightning strikes, thereby preventing damage to the connected system. GDTs offer protection against transient and direct current, and have been widely deployed in many industries to protect against a variety of electrical surges.CG7200MS Application Field and Working PrincipleThe CG7200MS is a Gas Discharge Tube Arrester made by Corning(R) and is designed to be used in low-voltage, high-power applications. The design of the arrester allows it to absorb lightning energy by effectively bypassing the surge current but limiting the voltage rise on the distribution line. The CG7200MS is designed to be used in applications such as high-voltage distribution systems and telecom equipment like remote switching centers and repeaters. The design of the CG7200MS makes it an ideal choice for surge protection in mission-critical applications.The CG7200MS uses a precisely-controlled gas-filled chamber that absorbs the high voltage energy of the surge and protects downstream equipment from being damaged or destroyed. When the surge voltage increases to the breakdown level, the gas in the GDT is ionized, and current is conducted between the electrodes. During this period, the energy is dramatically absorbed and the surge voltage is effectively clamped. The energy absorbed is not dissipated, but stored in the non-conductive dielectric material. When the energy is stored, the voltage is clamped below the breakdown value. The GDT then returns to the original off-state and absorbs the next surge.ConclusionGas Discharge Tube Arresters (GDTs) offer a reliable and cost-effective solution to protect sensitive electrical equipment against the damaging effects of lightning strikes and other transient overvoltage events. The CG7200MS is a highly reliable GDT designed by Corning(R) for low-voltage, high-power applications. It utilizes a precisely-controlled gas-filled chamber to absorb the high voltage energy from a surge and protect downstream equipment. The CG7200MS is ideal for mission-critical applications, such as high-voltage distribution systems and telecom equipment.
