Frequently Asked Questions
What is electromagnetic interference (EMI)?
Electromagnetic interference (EMI) is unwanted electrical noise that disrupts the operation of electronic equipment. It can be caused by power lines, motors, switching equipment, radio transmitters, and other sources. EMI can cause data corruption, equipment malfunction, false alarms, and safety hazards at critical facilities.
How does grounding reduce EMI?
A properly designed grounding system provides a low-impedance reference plane that prevents ground loops, reduces common-mode noise, and provides a controlled path for high-frequency interference currents. E&S Grounding Solutions designs grounding systems that address both power frequency and high-frequency EMI simultaneously.
What industries are most affected by EMI?
Data centers, telecommunications facilities, pipeline systems, medical facilities, manufacturing plants, and research laboratories are most affected by EMI. Any facility where sensitive electronic equipment must operate reliably in the presence of high-voltage power systems requires EMI analysis.
What does an EMI field measurement survey include?
An EMI field measurement survey includes in-field measurements using calibrated instrumentation at critical locations, identification and characterization of interference sources, analysis of coupling mechanisms, and a written report with targeted mitigation recommendations.
