Gas Discharge Tube Arresters (GDTs) are protection devices for electrical equipment from the effects of lightning or other high voltage, high current transients in an electrical system. GDTs are one of the most effective types of surge arresters for protecting equipment from overvoltage damage. The 2055-25-SM-RPLF is a surge arrester designed for Lightening Protection of Equipment. It can be used in Class I, II and II lightning protection systems.
GDTs such as the 2055-25-SM-RPLF work by controlling and dissipating potentially damaging transient high energy in a controlled manner. In its normal state, it allows a low-level electrical current, such as the ripple current from a power transformer, to pass through it with minimal impedance. In the event of an overvoltage spike, the GDT is triggered and changes state. The overvoltage current passes through the device which then controls the flow of current by shunting it to ground. Through this, the GDT is designed to protect the connected equipment from voltage surges. The GDT then returns to its original condition, ready to protect from any further unexpected high-energy transients.
The 2055-25-SM-RPLF is a three-phase GDT and is designed for 40.5 or 138kV system voltage. Its normal operating voltage range is between 18-28kV and its operating frequency is 50/60Hz. It has a maximum DC power frequency withstand voltage of IP=42kV. It has a DC discharge current of 60-155kA and a normal discharge current 8/20μs of 20kA. It has a thermal reference current of 10-250A and an operating temperature range of -40°C to 130°C. The GDT also has a minimum creepage distance of 280mm.
GDTs such as the 2055-25-SM-RPLF are mainly used in Medium Voltage (MV) electrical distribution systems in the industries of oil and gas, transmission and distribution networks, and renewable energy systems. These GDTs are used to protect transformers, switchgears, and other distribution devices from transient overvoltage in the systems. GDTs are also often deployed as a part of a Lightning Protection System (LPS), as it can provide an early warning system for lightning in order to protect more expensive equipment and personnel from damage.
In summary, the 2055-25-SM-RPLF is a gas discharge tube arrester designed for protection from lightning and other transient overvoltage situations. It works by controlling and dissipating damaging transient current, preventing damage to the equipment by shunting it to ground. The 2055-25-SM-RPLF is mainly used as a part of Lightning Protection Systems (LPS) in the industries of oil and gas, transmission and distribution networks, and renewable energy systems.
