This article provides a better understanding of the concept of equipment grounding and how to properly install grounding equipment.

This article explains the two kinds of grounds required by OSHA construction standards; system or service ground and equipment ground and also provides a summary of grounding requirements.

A good power distribution system is essential for proper operation of audio system. Professional audio systems just doesn't work well with normal extension cords running hundreds of feet to a stage. Besides the power feed the good grounding of the whole system is essential.

This question and answer article provides answers about various grounding questions, covering topics such as grounding remote buildings and strictures, transformer grounding, neutral and ground connections and generator grounding.

This article explains how isolated grounding systems work, how to install them, and when they should be used as well as sources of common-mode voltage and its effect on equipment.

Lightning, line surges or unintentional contact with higher voltage lines can cause dangerously high voltages to the electrical distribution system wires. Grounding provides an alternative path around the electrical system of your home or workplace minimizes damage from such occurrences.

This article offers tips on proper grounding techniques for various applications including NEC grounding, current sensing issues and alternative grounding solutions.

This article provides an understanding of the complex requirements of proper grounding. Topics like ground rod spacing, bonding jumpers, sizing equipment grounding conductors and ground loops are covered in detail.

If you've ever wondered how important a grounding system really is to the normal operation of a facility, just remember the alternatives: fires start from arcing faults; computers crash from spurious noise; data control systems shut down processes in error; human hearts "defib" and stop; motors burn up; arc-type lamps turn off (due to voltage imbalances caused by bad service bonding jumper terminations); voltage jacking occurs on ungrounded power systems or systems that have lost their grounding connection; and pipes spring leaks due to cathodic erosion.

This article outlines the conflicts and solutions involved with grounding revisions of the NEC for cathodically protected facilities.

This article explains ground-fault protection in a construction environment and how employing a GFCI can drastically reduce the dangers associated with construction work and electricity.

This article explains the importance of proper equipment grounding and bonding as well as performance of fault current paths.

Replacing many older aircraft ground servicing electrical systems, solid-state frequency inverters (SSFI) are primarily being used these days as a cost-savings initiative. Because the older systems were based upon a central rotating frequency changer (motor-generator) that operated 24/7, the energy and maintenance costs have become excessive. Point-of-use frequency inverters have lower operating and maintenance costs as they are energized only when needed.

This article explains how to identify and correct unwanted noise in audio/video recording applications by pinpointing the specific sources.

This article addresses reasons for ground testing including bonding problems, systems deterioration, and grounding system inequalities as well as what ground testing is.

This article answers five of the most frequently asked questions about grounding and ground-fault current including the advantages and disadvantages of various grounding methods, why it is necessary to ground the wye windings of transformers and generators and the reason for neutral-ground bonds at the secondary of a delta-wye transformer.

Ever wonder about the National Electrical Code's "25 Ohms or Less" rule? This article demystifies it and the importance it has, as well as discussing the grounding electrode system (GES) and testing.

Unwanted ground loops can cause inaccurate sensor readings by negatively affecting instrumentation signals. This issue is addressed in this article which details how an instrumentation signal loop works, the how and why of signal isolators, and also includes an instrumentation grounding primer.

Seen some sparks lately? The likely culpability lies with currents in the grounding electrode conductor. This article details how to effectively alleviate this situation and gives tips and warnings for working on the system.

The benefits and risks of the isolated ground wiring method are a function of many site variables, and they are discussed in this article, including where you can use an isolated ground (IG) connection, high and low-impedance loads and IG circuits, the importance of the length of the IG circuit, and noise and lightning problems.
