With increasing industrial automation systems also come the advancing and interconnecting systems of Industry 4.0; where communication is required to be as precise as possible between sensors, controllers and actuators. Despite all of this, one of the biggest hurdles to maintaining the efficiency and reliability of these systems is electromagnetic interference (EMI). It can also damage sensitive electronic components in so disrupted to errors, malfunction or even downtime in high critical operations. Therefore, they combat this problem by using line chokes to minimize EMI and to allow the smooth running of industrial automation systems.
What is EMI and Why is it a Problem?
Electromagnetic interference (EMI) is the interference with electrical circuitry that results from an electromagnetic field disturbance from an electromagnetic wave. Sources of EMI in industrial settings include motors, variable frequency drives (VFDs), power supplies and high frequency switching devices. With increasing electronic integration of automation systems, EMI induced into system performance is a risk.
EMI is able to cause erratic behavior in automation systems, including sending incorrect signals to a machine, getting unpredictable sensor readings, shutting down the entire system altogether. EMI is a serious concern for industries that are dependent upon uninterrupted processes, including manufacturing, automotive production, robotics.
How Line Chokes Help Reduce EMI
Line chokes, or inductors, are the devices used to restrict the quantity of high frequency noise and electromagnetic interference contained in an electrical circuit. Installed in series (with the power supply) they assist in smoothing out fluctuations, and help filter out noise before it can impact the electrical components.
When integrated into industrial automation systems, line chokes act as a buffer, protecting equipment from EMI by:
- Suppressing High-Frequency Noise: Line chokes decrease noise at high frequencies that produce EMI so automation has clean, stable power.
- Improving Power Quality: Line chokes reduce voltage spikes and harmonics — improving the quality of all power being delivered to machines and extending their life and efficiency.
- Enhancing System Reliability: As there are less disruptions due to EMI, automation systems usually suffer from fewer breaks and failures, hence, the overall reliability of industrial processes has improved.
The Role of Line Chokes in Industrial Automation
Line chokes serve an important role in maintaining system performance in industries that require precision and continuous operation. Often industrial automation systems are made up of motor drives, motors, controllers, sensors, and power supplies; they are all subject to EMI. EMI at critical electronics in these systems is mitigated by installing line chokes at key points.
To give an example, large factories with variable frequency drives (VFDs) generating electrical currents with a high speed switching effect generate EMI easily. VFDs use line chokes to reduce the harmonics and interference produced during motor operation, so that the automation system runs smoothly.
EMI can also disrupt communication between controllers and actuators, similarly, in robotic systems where precise movement control is of fundamental importance. Industries automate industrial systems by applying line chokes which filter the power to these components, because of which such systems can exhibit greater accuracy and less errors.
