Gas Discharge Tube Arresters (GDTs), such as GTCR37-201M-R10, are an integral part of power systems. They protect components and circuits from damage due to transient overvoltages originating from lightning or nearby switching operations. Designed to limit the effects of lightning strikes and power-line switching operations on power system and telecommunication equipment, GTCR37-201M-R10 Arresters provide a rugged, reliable and cost-effective solution for protecting systems from transient overvoltage events.

Functionally, GTCR37-201M-R10 Arresters have two states: high voltage bypass mode and arrester mode. When the system voltage is normal, the unit acts as a high voltage bypass. When a transient overvoltage event occurs, the arrester will divert the event away from equipment by providing a low impedance path to ground. The current is limited by the arrester’s own impedance. This arrester provides reliable surge protection for up to 10 kV.

The design of GTCR37-201M-R10 Arresters is simple yet effective. As is typical with Gas Discharge Tube Arresters, the two-stage construction involves a spark gap and a parallel discharge tube. The spark gap triggers the discharge tube to conduct current when a surge occurs. The spark gap’s static breakdown voltage should be higher than that of the system’s highest nominal voltage and lower than that of the expected maximum transient overvoltage. This design isolates the spark gap from the sustained breakdown voltage, preventing permanent damage to the arrester.

The primary application for GTCR37-201M-R10 Arresters is the protection of vital components and circuits from lightning strikes and power-line switching operations on power systems and telecommunications lines. Such transient overvoltage events can easily cause burnout of unprotected components, and arrester technology is a highly reliable and effective solution for limiting such damage. With its high surge current capability, the GTCR37-201M-R10 allows for a significantly lower risk of component damage than when using conventional protective components. Additionally, the arrester can also be used for transient protection of high-speed transmission lines.

Overall, GTCR37-201M-R10 Arresters provide a highly reliable and cost-effective solution for protecting systems from transient overvoltage events. With its simple yet effective design, the arrester is well suited for protection of vital components and circuits from lightning strikes and power-line switching operations on power systems and telecommunications lines. Additionally, it is also an effective solution for transient protection of high-speed transmission lines.
