Sample interview questions: How do you approach working on electrical systems with potential radio frequency interference (RFI)?
Sample answer:
Approaching Work on Systems with Potential RFI
-
Identify potential sources of RFI: Analyze the environment for equipment emitting radio frequencies, such as transmitters, antennas, and high-frequency machinery.
-
Evaluate the sensitivity of electrical systems: Determine the susceptibility of the systems to RFI by considering their design, shielding, and grounding.
-
Establish mitigation strategies: Implement measures to minimize the effects of RFI, such as:
- Using shielded cables and connectors
- Grounding all conductors properly
- Installing EMI filters and suppression devices
- Separating sensitive circuits from potential interference sources
-
Consider specialized equipment: Utilize equipment specifically designed to handle RFI, such as shielded enclosures, fiber optic communication, and noise-canceling devices.
