Gas Discharge Tube Arresters (GDT)

Gas Discharge Tube (GDT) Arresters are widely used in international electrical power systems for the protection of transformers, rotary machines, surge arresters, and other electrical devices. GDTs are used in order to protect them against voltage transients, lightning, and other abnormal environmental conditions. These electrical devices are subject to the selection of suitable voltage levels and current limits of capacitive voltage dips, over-voltage surges, and excessive over-currents. The GDT arrester works by allowing a specific amount of current to pass through it as long as the current is lower than a set threshold value. When the current is higher than the threshold value, the arrester will halt the current by breaking down the applied voltage.

CG2250MS is a gas discharge tube arrester with a rated voltage of 2.5kV and a high coupling voltage of 5.5kV. It can be used in telecommunications, oil and gas pipelines, electric power systems, and industrial applications. It can offer a high breakdown voltage, fast response time, and a wide frequency range, making it suitable for use in various environments. The device has excellent durability and can be used in wet, dry, salty, hot, and cold climates. The CG2250MS is able to withstand short-term overvoltage or overcurrent events while still operating with a stable voltage, and it is able to provide the desired protection to the electrical device or system when connected.

The working principle of the CG2250MS arrester consists of two steps. First, a dielectric material is used to produce a spark discharge that captures and stores energy whenever a high-voltage surge is detected. During the second step, the energy is discharged back into the system, suppressing and discharging any possible surges or overvoltages before they can damage the system. This reliable protection ensures that the arrester does not cause any further harm or disruption. Furthermore, the arrester makes use of a field-effect transistor (FET) to regulate the amount of energy that is discharged. The FET is able to detect the level of the high voltage and discharge a preset amount of energy, such that it does not cause any further harm to the system.

The CG2250MS arrester is a highly reliable and durable product that can provide protection against electrical transients in various applications. Its features make it suitable for use in telecommunications, oil and gas pipelines, electric power systems, and industrial applications. It can withstand short-term overvoltage and overcurrent events while still functioning reliably and providing protection to the system or device. Moreover, the arrester uses an FET to regulate and limit the amount of energy that it releases in order to prevent any further harm to the system and ensure its reliable protection.
