About Film Covered Flat Aluminium Wire
The purpose of grounding the instrumentation and control system in a chemical plant is primarily to ensure the safety of personnel and the reliable operation of electrical equipment. Additionally, it plays a crucial role in the transmission of instrument signals and the prevention of interference. Grounding provides a low-impedance path for current to return to its source, which helps reduce faults and errors in the automation and control system once the instruments are installed.
In field applications, proper grounding is essential for various types of instruments such as flowmeters, transmitters, RTDs, pressure transmitters, and level gauges. Each of these devices requires specific grounding methods to function correctly and safely.
Instrument grounding can be classified into several categories, including protective grounding, working grounding, intrinsically safe system grounding, anti-static grounding, and lightning protection grounding.
Protective grounding, also known as safety grounding, is used to protect both people and equipment from dangerous voltages that may occur due to insulation failure or other faults. It ensures that any fault current has a safe path to ground, preventing it from passing through a person’s body. For example, metal enclosures of electrical devices should be grounded to prevent electric shock hazards.
Shield grounding is another important type, aimed at reducing electromagnetic interference (EMI) and capacitive coupling. Shielded cables, drain wires, and shield terminals must be properly grounded to maintain signal integrity and minimize noise.
Lightning protection grounding is critical when instrument signal lines enter a building from outside. These systems should be connected to the main electrical lightning protection system, but not shared with independent lightning rods. Proper connection of cable troughs, conduits, and field instrument grounding points is necessary to prevent damage from lightning strikes.
Common issues in field instrument grounding include improper grounding of surge modules, incorrect grounding of cable armor and shielding layers, and insufficient cross-sectional area of grounding conductors. Ensuring that all grounding connections are clean, continuous, and well-maintained is vital for the reliability and safety of the system.
In PCB design, separating analog and digital grounds helps reduce noise interference. Shielding should be connected to the interface ground rather than the signal ground to avoid noise coupling. Interface grounding for external connectors like serial ports and RJ45 jacks should be carefully designed to prevent electromagnetic interference and ensure stable communication.
Proper grounding practices are fundamental to the safe and efficient operation of instrumentation and control systems in industrial environments. Regular maintenance and adherence to standards are essential to avoid potential hazards and system failures.
