Gas Discharge Tube Arresters (GDT) is an electrical device used to protect electrical power systems and equipment from lightning strikes and other overvoltage events. The SL1021A500RF is a Gas Discharge Tube Arrester (GDT) designed for high-voltage power applications. It is a metal-oxide varistor (MOV)-based device that is used to protect the core components of a power system from over-voltage and over-current events.

The SL1021A500RF is a Gas Discharge Tube Arresters (GDT) that works on the principle of “calorific dissipation”. This principle states that when a high surge of energy passes through the device, the resulting thermodynamic process results in the release of heat into the air. This process helps to dissipate the energy and ultimately helps to protect the power system from permanent damage.

The SL1021A500RF is designed for high-voltage power applications and is rated to protect up to 500V. It is constructed with a metal oxide varistor (MOV) that helps to absorb the energy from power surges and provide a path for it to be safely dissipated into the environment. This device also has a stationary and moving contact that allows for arc extinguishing. This helps protect the device from potential arc heating and ensures reliability.

SL1021A500RF application fields primarily include, but not limited to, 4160/7200V industrial power transmission equipment, power transformers, terminal power, high-rise building power, high-voltage switchgears, urban and rural grids, power electronic components, and more. It helps protect these electrical components from potential damage caused by surges in voltage and current.

When installing the SL1021A500RF, the device must be connected between the power source and its load. This device should be installed between the load and ground so that the surge of energy can be diverted to the ground and dissipated in an safe manner. It is important to ensure that the device is installed in a location where it is safely away from other electrical components, as its high energy can cause irreparable damage.

Once in the system, the SL1021A500RF works with a specific trip characteristic. It is designed to “trip” the circuit at a given voltage, regardless of the current on the line. When the overvoltage event occurs, the MOVs divert the energy out of the system, dissipating it as heat. The device then resets, and the protection circuit is returned to normal.

The SL1021A500RF is an important device for protecting electrical systems from overvoltage and overcurrent events. This Gas Discharge Tube Arresters (GDT) is designed for high-voltage applications and is rated to protect up to 500V. The design of the device and its stationary and moving contacts make it highly reliable and efficient. Plus, it can be easily installed in the system with the correct protective setting.
