Sample interview questions: How do you approach working on electrical systems with potential electromagnetic pulse (EMP) concerns?
Sample answer:
-
Identify and Assess Potential EMP Concerns:
-
Conduct a thorough risk assessment to identify potential sources of EMP, such as nearby power lines, transformers, or radio transmitters.
-
Evaluate the susceptibility of the electrical system to EMP, considering factors like the type of equipment, shielding, and grounding.
-
Use Shielded and Surge-Protected Components:
-
Employ shielded enclosures, cabinets, and cables to minimize the effects of EMP on sensitive electrical components.
-
Install surge protection devices (SPDs) to divert and absorb transient voltage spikes caused by EMP.
-
Implement Proper Grounding and Bonding:
-
Ensure adequate grounding and bonding of the electrical system to minimize potential differences and reduce the risk of damage.
-
Employ multiple grounding points to improve the overall grounding effectiveness.
-
Use Fiber Optic Cables for Communication:
-
Utilize fiber optic cables for communication instead of copper cables, as they are less susceptible to EMP interference.
-
Implement proper termination and splicing techniques to maintain signal integrity.
-
