In lightning protection system design, many people often hear terms such as rolling ball, protection level (LPL) or radius D, but do not really understand their role and application. This article will help clarify the core technical concepts to choose the right type of rod and the right solution for each project.

RS communication systems (RS232, RS422, RS485) are often deployed in industrial and commercial environments where there is a high risk of lightning and electrical interference.

Ethernet is the most widely used local area network (LAN) technology today, allowing devices to connect and communicate with each other on the same network by transmitting data in frames over connecting cables, ensuring stable performance and high speed.

RS232, RS422, RS485 are popular serial communication protocols, they play an important role in connecting control, measuring and monitoring devices.

Fipway is an industrial communication standard developed by Schneider Electric, designed to provide useful information about the status of installed equipment, to optimize uptime and operational efficiency.

The 4-20mA signal is a form of current signal commonly used in the field of industrial control and measurement to transmit data between devices, such as sensors and controllers.
