Good grounding practices - Part 2

Transfer of the immediate discharge of the electrical energy directly to the earth by means of the low resistance path is known as the earthing. Main objective of the earthing system in plant is described as below:. Items or equipment which require earthing, are but not limited to below,. This article mainly focuses on earthing requirements for instrumentation items of any industrial plant. There are mainly 3 types of earthing systems provided for instrumentation. Undetected earth faults pose safety risks to personnel also may lead to safety hazards such as equipment malfunctions, fire, and electric shock.

Our website is packed full of both free and paid-for content, including:. Our aim is to help people learn how to more quickly and cost-effectively design and manufacture electronic equipment products, systems, installations, etc. Such equipment should benefit from reduced warranty costs and financial risks, whilst improving uptime, competitiveness and profitability. Find your EMC Standards quickly and easily What EMC issue do you want to learn about today?

Scope: This function of this guide on shielding practice for low voltage cables is to inform and familiarize the reader with shielding practice. An overview of shielding practice, systems, and test methods is provided. These tests may not be standardized; however, they are included to inform the reader and provide an overview as to what has been done to characterize shielding. This guide provides the following: -An enumeration of sources of electrostatic and electromagnetic interference -A review of shielding techniques to control electrostatic and electromagnetic interference for varying types oflow voltage cable uses for power, control and instrumentation services, including signal and communications cable -An overview of the functional characteristics of various types of shielding -Criteria for defining the most favorable techniques to combat interference -Suggested tests or techniques for measuring shielding effectiveness -Recommendations on shielding practices, including suggestions on terminating and grounding methods.

Post a Comment. Practical Grounding, Bonding, Shielding and Surge Protection is a practical engineer's guide to the areas of grounding, shielding and surge protection designed to deliver reliable equipment and communications systems that comply with international and national codes. Practical Grounding, Bonding, Shielding and Surge Protection unlike many books on grounding and shielding, provides straight-forward, practical solutions to commonly encountered real-world situations and enables one to better understand proper ground methods and to quickly recognize and solve existing grounding issues in a facility. Also, it covers not only low voltage grounding techniques but also power system grounding, which is generally not well covered in literature. There are some very good examples illustrating how motor start-ups can induce a noise signal in signal cables through capacitive coupling into the conduit supplying the power to the motor. There are also many cases showing how ground loops can be formed and ways to prevent them.

When asked to quantify what such a ground is, they generally talk about a ground not connected to that dirty, nasty power ground. It seems they expect that noise or problems will somehow arise out of the ground and strike down their equipment. This is basically a question of whether to have a separate, isolated hence somehow clean , instrument ground, or to have it a part of the overall facility grounding grid.
