The Gas Discharge Tube Arresters (GDT) are devices used to protect electrical equipment from damage that can be caused by antennas, lightning strikes, and switching equipment. The GTPN28-231M-R20 is a type of GDT designed to serve many different types of applications. This article will discuss the application field and working principle of the GTPN28-231M-R20.

The GTPN28-231M-R20 was designed for use as a surge arrester in AC low voltage systems or DC systems. This arrester is intended for indoor application and consists of a metal oxide element inside of an aluminum can. It is capable of handling 1000V surges up to 25kA. The GTPN28-231M-R20 has an operating temperature range of -40°C to +85°C and a storage temperature range of -25°C to +85°C. It has a rated voltage of 14V and a maximum leakage current of 11mA. The arrester has low capacitance and no maintenance requirements.

The working principle of the GTPN28-231M-R20 is based on gas-filled spark gaps, which are made up of two metal contacts separated by a spark gap. When a surge is applied, the spark gap creates an electric arc which is conducted into the ground and thereby limits the overvoltage across the spark gap. The GTPN28-231M-R20 is also equipped with fuses to protect its components in the event of a high-energy surge. The arrester is designed with a metal oxide element that serves to absorb the energy from the sparks and protect the connected electrical equipment from damage.

The GTPN28-231M-R20 is used in various industries and applications including telecommunications, power distribution, railway systems, and data centers. In telecommunications, it is used to protect phone lines and equipment from surges caused by lightning strikes. In power distribution, it is used to protect power lines and substations from transient voltage surge. In railway systems, it is used to protect signaling and communication systems from transient voltage surge. In data centers, it is used to protect electronic equipment and computer systems from unanticipated surges.

The GTPN28-231M-R20 is highly reliable and offers a superior level of protection. It is designed for easy installation and maintenance and comes with a five-year warranty. This arrester is suitable for a wide variety of applications and is a great choice for protecting critical systems. The GTPN28-231M-R20 is an effective and reliable gas discharge tube arrester that provides superior protection against transient voltage.
