Engineers view grounding mainly as a method to protect equipment from damage or malfunction. Hence, the most
important element is operator safety. Proper grounding is a basic protection against AC line disturbances. This applies whether
the source of the disturbance is lightning, power-system switching activities, or faults in the distribution network. It is also a key
element in preventing radio frequency interference in transmission or computer equipment. Moreover, power quality can be
significantly degraded due to improper grounding. Implementing an effective ground network is not an easy task. It requires
planning, quality components, and skilled installers. It is not inexpensive. However, proper earthing is an investment that will
pay dividends for the life of the facility.
