Gas Discharge Tubes (GDT) are an important component of power systems. They provide reliable protection for electric networks and equipment against lightning and other transient pulses. This article provides an in-depth understanding of 2047-15-ANI application field and its working principle.

What is 2047-15-ANI?

2047-15-ANI is a special type of Gas Discharge Tube (GDT) arrestor, also known as a Relay Arrestor. Its main purpose is to protect equipment in a power system by safely limiting the transient over voltages generated by lightning strikes and other electrical disturbances. The 2047-15-ANI is a bi-directional, unidirectional 3-pole GDT arrestor, meaning that the overvoltages hitting each of its poles will be limited in both directions. It is also a silver-plated GDT, meaning it can handle significantly higher voltage levels than other GDTs.

Application Field of 2047-15-ANI

The 2047-15-ANI GDT arrester is suitable for the protection of overhead power equipment as well as industrial, commercial and domestic equipment. It can be used to protect power networks from damaging lightning or other over voltages for a wide variety of applications such as lightning protection systems, power distribution grids, electrical equipment and data networks. It is also suitable for earth-wire connection in isolated medium-voltage grids.

Working Principle of 2047-15-ANI

The working principle of the 2047-15-ANI GDT arrester is based on the breakdown of a “mini spark gap” within the device that is triggered when an over voltage surpasses the normal rated operating voltage of the system. When an over voltage is applied, the gas inside the tube ionizes and the current is diverted around the discharged path, providing a safe low-impedance protection path. This causes the overvoltages current to be safely limited and dissipated into the ground, thus preventing any damage to the power system equipment.

The 2047-15-ANI GDT arrester is designed to absorb transient overvoltages and dissipate them into the ground very quickly, while still allowing equipment to continue operating at normal levels. The device also has a limited peak voltage capability in order to avoid damage to the arrestor itself in case of a severe overload. To ensure reliable operation over time, the 2047-15-ANI arrester is designed to self-extinguish when the overvoltage pulse is removed.

Conclusion

In conclusion, 2047-15-ANI GDT arresters are a reliable and cost-effective solution for protecting power equipment from damaging transient over-voltages. Its working principle is based on the breakdown of the “mini spark gap” within the device and its design ensures reliable operation over time. The 2047-15-ANI can be used for a wide variety of applications, ranging from lightning protection systems to earth-wire connection in isolated medium-voltage grids. It is also suitable for overhead power equipment as well as industrial, commercial and domestic applications.
