HVL-1/2

High Voltage Limit (HVL) fuse technology has become increasingly important in protection of high voltage systems. HVL-1/2, also known as Isolated Phase Bus (IPB), is a general type of high voltage thermal fuse. It is designed primarily for overload and short circuit current limitation in electrical systems. It is typically used in systems that employ open or enclosed bus duct systems. The HVL-1/2 technology is especially popular in America and Japan.

The working principle of HVL-1/2 is based on the thermal-electric arc interruption principle. When the current entering the fuse exceeds its rated current, through a well-designed structure, an arc will be generated. The HVL-1/2 fuse then acts to absorb and dissipate the thermal energy from the arc to protect the system. This in turn prevents the current from rising to an explosive level, thus providing the system with an extremely high level of current limitation and protection.

HVL-1/2 technology can be employed in a wide variety of applications. It is commonly used in high voltage systems that require over-current protection for such applications as motor protection, emergency power control, automatic transfer switch protection, and even critical instrumentation protection. The use of the HVL-1/2 also provides an increased level of safety due to its exceptional current limiting capabilities. It is also widely used in all types of stationary or mobile power generation and distribution equipment, as well as for many other general industrial applications.

The HVL-1/2 is known for its superior current limitation abilities, and as a result, is able to efficiently handle large fault currents and protect systems in a reliable and safe manner. This technology can also help to increase the reliability of a system by limiting the amount of energy that can pass to a system in the event of an overload. Therefore, the system is better protected from equipment and system failures than with other traditional fuse technologies.

HVL-1/2 technology is simple to use and provides superior performance in comparison to other types of over-current protection. It is also relatively cost effective for large current limiting applications, making it one of the best options for high voltage systems. The technology also offers a high level of reliability and safety, making it an attractive option for use in electrical systems.

Overall, the High Voltage Limit (HVL-1/2) fuse technology has become increasingly important in protection of high voltage systems. Its use provides system reliability, safety, and cost savings. With its superior current limiting capabilities, the HVL-1/2 has emerged as an indispensable fuse technology for applications in high voltage systems.
