The GTCA28-102M-R03 Arrestor is one of the components that defines the reliability of any given system under electrical power flows. As a piece of effective lightning protection, this component is a Gas Discharge Tube Arrestors (GDT) with a working principle of gas insulation that specializes in direct current (DC) and alternating current (AC) power systems. This article will present the application field and working principle of the GTCA28-102M-R03 Arrestor.The GTCA28-102M-R03 Arrestor is a type of Gas Discharge Tube Arrestor (GDT) that applies to AC and DC systems with a nominal voltage range of 0kV to 250kV. It is a component specially designed to protect against lightening and other overvoltage surges. In addition, it can be used in non-grounded AC, grounded AC, high impedance grounded and low impedance grounded system. This unit is also equipped with a self-check circuit that can verify the normal operation of the unit, thus allowing the user to be confident on its safety levels at all times.The working principle of the GTCA28-102M-R03 Arrestor is based on the principle of gas insulation. When an over or undervoltage that exceeds the breakdown voltage of the gas discharge tube inside the Arrestor is encountered, a short-circuit current will develop and dissipate in the gas-filled enclosure. This generated current is then regulated and controlled by the voltage clamp circuit to provide a limit for the voltage that can pass through the Arrestor. This ensures that the voltage at the output side of the device stays within a safe working range and that no damage is caused to the equipment connected in line with it.In addition to the voltage clamping, the GTCA28-102M-R03 Arrestor also features a spark diverter coil which helps to reduce the level of stress on the unit’s voltage terminals. This helps to minimize the risk of arcing or sparking on the voltage terminals, thus ensuring maximum safety.In addition to providing lightning protection, the GTCA28-102M-R03 Arrestor can also help to reduce the impact of noise interference on sensitive electrical components. It does this by reducing the amplitude of surges generated along the power line, thus helping to reduce the risk of component wear or failure.To conclude, the GTCA28-102M-R03 Arrestor is a Gas Discharge Tube Arrestor (GDT) that provides efficient lightning protection and noise interference reduction on AC and DC systems with a nominal voltage range of 0kV to 250kV. Its working principle is based on the principle of gas insulation. When over or undervoltage is encountered, the component provides a voltage clamp circuit which helps to regulate and control the generated current to a safe working range. In addition, it also features a spark diverter coil which can help to reduce stress on the voltage terminals.
