Gas Discharge Tube Arresters (GDT) are widely used in all kinds of power systems for over-voltage protection. They are one of the most reliable and cost-effective protection devices. The PMT835006 is a type of GDT which has many advantages and a wide application range. This article will provide an overview of the PMT835006 application fields and working principle.

Application Fields

PMT835006 can be used in all kinds of power systems which includes electricity grid, telecommunications, and gas and petroleum systems. It can be used for both TVS and lightning protection. It can also be used for over-voltage protection of sensitive and expensive equipment such as networking equipment.

This device also has various advantages compared to other protection devices. It has a very fast response time which up to 1 microsecond. It also has a very wide operating voltage range from 25 VDC to 2,500 VDC. Furthermore, it can withstand up to 10,000 strikes per minute. This makes it ideal for applications where lightning frequently strike.

The PMT835006 GDT also possess a high energy dissipation capability which can protect components from overvoltage damage during lightning storms or when the power system is switched on. It has a low heat generation rate which makes it suitable for high temperature environments. It also has low after-restrikter DC leakage current which is important for the protection of sensitive electronic equipment.

Working Principle

The PMT835006 gas discharge tube works by providing a spark gap in front of the devices. It consists of a sealed glass tube that is filled with a gas mixture, typically air, nitrogen and argon. When a surge or overload passes through the arrester, the voltage instantaneously develops a spark, which instantly ionizes the gas molecules and creates a highly conductive path. This path provides an outlet from the arrester outlet to ground, thus limiting the voltage on the system by diverting the surge away.

Once the spark has been created, the gas molecules quickly recombine and the arrester is no longer conductive. The amount of time during which the arrester is conducting is known as the spark cycle. The spark cycle is normally only a few hundred nanoseconds in duration but in larger surges, the spark cycle may be extended up to 1 microsecond or more.

The PMT835006 GDTs are designed to meet the latest IEC and ANSI standards for surge protection. Its robust design allows the user to choose from a wide range of protection levels, from Class B to Class E depending on the application.

The PMT835006 GDT is an ideal protective device for use in high-voltage systems. It is fast in operation and has a high energy dissipation capability which can provide superior overvoltage protection to sensitive and expensive equipment. Its robust design and wide operating voltage range make it a great choice to protect against surges and lightning.
