Introduction

Gas Discharge Tube Arresters (GDT) are widely utilized in power system operations to limit the over-voltages and avoiding any sort of breakdown. They are designed to protect against lightning, fault currents, and other disturbances. The GTCS28-750M-R20-2 is a highly reliable GDT of type S-2, which provides excellent protection against lightning and other high voltage and high frequency surge events.

Application Field

The GTCS28-750M-R20-2 is an ideal solution for applications such as the protection of communications lines, electric distribution networks, CATV, or antenna systems. It is also suitable for usage in high voltage installations, powering equipment, and other high-voltage capacitor applications. It has a high dynamic resistance level to minimize the operational current in situations of over-voltages and a high surge capacity to handle lightning strikes and other power quality events. Additionally, the housing is designed as an anti-humidity shell, making sure that the GDT is working under normal conditions.

Working Principle

The GTCS28-750M-R20-2 works by discharging surge overvoltage energy from the power system, through an integrated arc overvoltage protector element or gas discharge tube. This design works by discharging arc, causing the overvoltage to drop to a safe level and isolating the protected system from the surge. The protective element is a miniature gas discharge tube with an internal breakdown voltage. When the power system voltage exceeds this breakdown voltage, the protective element triggers and discharges surge energy.

Conclusion

In conclusion, the GTCS28-750M-R20-2 is an efficient and highly reliable GDT, suitable for a wide variety of protective applications. Its integrated arc overvoltage protector element and gas discharge tube design allows for robust protection against lightning, fault currents, and other high voltage and high frequency surge events. It is an ideal solution for high voltage installations, powering equipment, communications lines, electric distribution networks, CATV, and antenna systems.
