1. which of the following are the two main concerns with lightning protection?

(a.) the diversion of the lightning current away from the protected structure
(b.) limiting of currents and voltages induced on power and communications systems by means of surge protective devices (spds)
(c.) the cost of proper protection systems
(d.) (a.) and (c.)
(e.) (a.) and (b.)
(f.) (b.) and (c.)

a

b

c

d

e

f

Explanation:

To determine the two main concerns with lightning protection, we analyze each option:

• Option (a) involves diverting lightning current from the protected structure, which is a key concern in lightning protection (e.g., using lightning rods or grounding systems to channel the current safely).
• Option (b) involves limiting induced currents/voltages on power and communication systems using surge protective devices (SPDs), which is also a critical concern as these induced effects can damage equipment.
• Option (c) (cost) is a secondary or practical concern, not a main technical concern of lightning protection.

So the two main concerns are (a) and (b), which corresponds to option (e).

Answer:

e. (a.) and (b.)
