Gas Discharge Tube Arresters (GDT) are essential components of high-voltage environments, suppressing potentially dangerous high-voltage pulses. The PMT6090MS is a type of GDT arrester, designed for use in exposed and non-exposed areas, and in both AC and DC environments. Its main function is to protect DC or AC HV electrical transmissions,substations, power and telecom systems, isolated neutral lines, and earthing systems.

The PMT6090MS works by treating high-voltage surges or spikes as they arrive. As high-voltage is coming in, the GDT acts as a resistance element that helps dissipate or reduce the intensity of the voltage ,so that it doesn’t cause damage to system components. It is designed to be easy to install and maintain, and its temperature coefficient of resistance ensures that the arrester automatically adjusts its resistance so it can function effectively in different temperature environments.

The PMT6090MS is made from metal oxide varistor (MOV) material. This MOV material has a uniform, symmetrical, non-linear resistance-time characteristic that allows it to act as a surge current limiter. This material has the ability to quickly absorb a surge current and then quickly release it in order to protect the device, as well as other system components.

In addition, the PMT6090MS is rated to withstand up to 8/20 μs lightning impulse currents and high potential testing. It is also designed to be environment-friendly, with low carbon emissions and an improved environmental safety index of 94. All these features make the PMT6090MS an ideal choice for a variety of applications.

The PMT6090MS can be used in a variety of applications such as power transformers, AC/DC HV electrical transmissions, telecommunications systems, telecommunications towers, isolated neutral lines, and earthing systems. It can also be used in various types of power and telecom systems, as well as in industrial and public buildings.

In terms of its working principle, the PMT6090MS works by conducting various high-voltage surges and then dissipating or reducing the absorption of the surge energy. This is achieved through the characteristics of the MOV material, which has a non-linear resistance-time characteristics. This material can absorb surge energy quickly and then release it quickly in order to protect the device, as well as other system components.

The PMT6090MS is designed to have a low operating temperature coefficient of resistance, so that it can effectively work in different temperature environments. It also has a fast response time, allowing it to easily handle high-voltage surges as they occur. This ensures that the arrester is able to effectively protect the device as well as other system components.

Overall, the PMT6090MS is an essential component for high-voltage applications and environments, and it efficiently absorbs and dissipates surge energy to protect the device and other system components. Its temperature coefficient of resistance ensures that it functions effectively in different temperature environments, while its fast response time helps protect the system from high-voltage surges.
