The selection & installation of SPD is a Specialist job, as the installer shall have thorough knowledge on the current Indian & international standards along with hands-on experience because there are challenges related to each site.

A variety of devices provides over-current protection, but Surge protection devices are the only ones that can safeguard sensitive electronic equipment from overvoltage caused by contaminated power sources and the increasing use of non-linear devices.

It is well-known fact that lightning surges are more destructive than switching surges. Research reveals that switching surges cause far more faults and early failures of sensitive electronic and electrical equipment than lightning surges because there are many sources of switching surges.

CNC stands for computer numerical control, which is the automated control of machining instruments like drills, lathes, mills, and 3D printers using a computer. The introduction of CNC machines during the 1950s has radically changed the manufacturing industry.

In the recent article, we read about the sources of surges in Industrial & Commercial Power Systems. In this article, we will analyses solutions to protect electronic equipment from surges.

Lightning surge protector devices excess voltage and current from transient and surge events diverted onto grounding wire, stopping them from passing through electrical and electronic equipment while allowing regular voltage to continue on its course.

Earthing is always the first line of defense when it comes to electrical safety.Reliability of the LV is a very important and essential electrical safety and stability.It is understood and accepted that a reliable Earthing system is required for the safety of humans and equipment that are connectedwith an electrical system.
