Gas Discharge Tube Arresters (GDTs) are electrical protective devices that protect sensitive electrical and electronic equipment from transient overvoltages resulting from lightning, electrical switching and faults. GDTs are composed of electronics and electrical components which form a closed loop that is designed to conduct energy caused by a transient event away from sensitive circuits.

The 2027-23-A is a type of GDT that is commonly used in industrial and commercial applications. It is designed to reduce or eliminate sustained overvoltages such as power line surges, faulty electrical wiring, or induced surges from lightning. By providing a low resistance path for overvoltages, it acts as a protective barrier between the primary power circuit and the sensitive equipment, minimizing or even eliminating their destructive effects.

The 2027-23-A consists of an internal electrical discharge tube (EDT), an external discharge tube (EDT), a spark gap, a capacitor and a resistor. The EDTs are designed to reduce the voltage between two points to an acceptable level by discharging any excess voltage or current to ground. The spark gap can further reduce the voltage by providing a low voltage carrying path for transient pulses. The capacitors are used to store the energy from the transient pulses, helping to reduce the magnitude of the voltage spike to a more manageable level. The resistor helps to absorb any residual energy from the transient pulses.

In operation, the 2027-23-A works by providing an electrical path to dissipate the energy from the transient events. The primary circuit is connected to the EDTs. When an overvoltage occurs, the EDTs are designed to act as a low resistance path, thereby preventing the overvoltage from damaging sensitive circuits. The spark gap then provides an additional low resistance path, further reducing the magnitude of the voltage. The capacitor and resistor then store and absorb any residual energy from the event, thus limiting the damage caused to the circuits.

The 2027-23-A is designed to protect electronic circuits and devices from transient overvoltages, helping to prevent long-term damage or malfunctions that can result from prolonged exposure to high voltage. Its highly efficient circuit design minimizes the amount of energy that must be dissipated by the EDT. The spark gap, capacitor and resistor provide additional protection, further reducing the risk of damage to the circuits. This makes the 2027-23-A ideal for applications where sensitive electronics or equipment must be protected from the damaging effects of transient overvoltages.
