CG90LSSN and Its Working Principle

Gas Discharge Tube Arresters (GDT) are widely used in power systems for the protection of equipment from indirect lightning discharges. CG90LSSN is a GDT designed for application in low and medium voltage systems. It is a gapped spark gap arrester equipped with an overvoltage monitor. This article discusses the working principle of CG90LSSN and its application in low and medium voltage systems.The general construction of CG90LSSN is like a two-stage arrester. It has two main components - a spark gap arrester and an overvoltage monitor. The spark gap arrester consists of two electrodes with a spark gap between them. The overvoltage monitor is integrated with the spark gap arrester and comprises of an electromagnetic core wound with a coil.The spark gap arrester has a number of electrodes, which are connected in series. Each electrode has a spark gap that is tuned to a specific voltage level. When the overvoltage monitor senses an overvoltage, it causes the spark gap to open, resulting in the release of sparks. This helps to dissipate the excess voltage.When the overvoltage monitor detects a surge, it triggers the spark gap arrester to open, thus dissipating the surge. The spark gap arrester also has a spark gap resistive component, which helps to reduce the surge voltage. The combination of the spark gap resistive component and the overvoltage monitor helps CG90LSSN to protect low and medium voltage systems from electrical surges, switching surges, lightning strikes and other indirect lightning discharges.The working principle of CG90LSSN is quite simple and straightforward. The arrester is connected in parallel with the load, which means that any voltage between the power source and the load will be diverted to the arrester. When the voltage across the arrester exceeds the specified limit, the overvoltage monitor will activate and cause the spark gap to open. This helps to divert the excess voltage and prevents it from harming the load.CG90LSSN is a highly reliable GDT suitable for use in both low and medium voltage systems. It is easy to install and requires minimal maintenance. It is also cost effective, making it an attractive option for those looking for efficient protection from electrical surge and lightning discharge.The CG90LSSN GDT is a reliable and cost-effective way to protect electrical systems from lightning discharges and electrical surges. It is easy to install and requires minimal maintenance. It is also compact and lightweight, making it suitable for various applications. The combination of its spark gap arrester and overvoltage monitor makes it a versatile arrester capable of providing effective protection.
