Lightning Protection
Industrial installations and power plants are normally provided with well-integrated
grounding networks, installed as part of the power distribution system. Such
installations do not require additional lightning protection.
Additional lightning protection is always necessary when:
•
Cables extend beyond the area covered by the ground line network
•
Cables are located above ground
•
Overhead cables are used.
Inductive Load Suppression
Inductive loads, such as relays and contactors connected directly to products, do not
require suppression. The necessary suppression components (varistors or snubbers-
RC units) are installed on the circuit boards.
