Grounding is defined as electrical equipment connected directly to mother earth, or to some conducting body that serves in place of the earth, such as the steel frame of a high-rise building on a concrete footing. Proper grounding is an essential component for safely operating electrical systems. Improper grounding methodology has the potential to bring disastrous results. There are many different categories and types of grounding principles. This paper’s focus is to demonstrate proper grounding techniques for low voltage Instrument and Control Systems (IACS) that have been proven safe and reliable when employed in gas measurement facilities
