Gas Discharge Tube Arresters (GDT):

Gas Discharge Tube Arresters (GDT), also known as "spark gaps" or surge suppressors, are electrical components used to protect electric circuits from disturbances and voltage spikes caused by short circuits or lightning strikes. GDTs are typically made of two electrical contacts enclosed in an insulating material.When a transient voltage (caused by a lightning strike or a switch turning on or off) exceeds the breakdown voltage of the GDT, electrical current passes through the GDT, allowing the voltage to dissipate without damaging the electric circuit.

GTCS28-750M-R10 is a Gas Discharge Tube from a series of products manufactured by G&R Technology. The GTCS28-750M-R10 is a reliable Surge Protective Device (SPD) designed for industrial and commercial applications. It features simple installation requirements and is capable of handling transient overvoltages up to 750 volts.

The GTCS28-750M-R10 provides superior resistance against transients with its built-in integrated parallel capacitors and MOVs. This makes it suitable for use in a variety of applications where exceptional speed in dissipating transient overvoltages is required.

The GTCS28-750M-R10 application field includes residential and industrial locations, as well as in industrial motor protection, inductive loads, automobiles, data communication networks and other equipment that may be subject to lightning and electrical noise. It is also suitable for powerline to ground, and powerline to powerline surge protection.

Working Principle

Gas Discharge Tube Arresters use a gas-filled tube, also known as a spark gap, to quickly reduce voltage when a transient surge is detected. When the surge detection takes place, the voltage-dependent gas in the spark gap starts to conduct electricity until it reaches a given voltage, at which point the spark gap abruptly shuts off. This process allows excessive voltage to be safely deposited into the spark gap before it reaches the rest of the electrical system. This prevents voltage spikes and surges from damaging electrical equipment.

The GTCS28-750M-R10 works by connecting two GDTs in parallel. During a surge event, the first GDT allows current to pass freely, while the second GDT rapidly decreases the voltage. This process allows the voltage to dissipate safely, preventing any damage to the rest of the electrical system. The GTCS28-750M-R10 also features integrated components such as a MOV and capacitors, which provide enhanced protection and fast response time.

The GTCS28-750M-R10 is an effective solution for protecting electric circuits from damaging transients and voltage spikes. It is suited for all kinds of industrial and commercial applications, and its integrated components enable faster response and greater protection from electrical disturbances.
