I-Gard has the most comprehensive Technical Library in the industry.

Popular amongst customers and competitors alike, the I-Gard Technical Library is also the most current thinking available on the subjects of ground fault protection and power resistors.

In conjunction with industry leading trade magazines such as Electrical Business, Electricity Today, International Association of Electrical Inspectors, Plant etc., I-Gard has furthered the understanding of the hazard of arcing faults as well as the benefits and applications of high resistance grounding through a number of educational editorials. I-Gard regularly updates the Application and Specification Guides, relied on by consultants, end users and contractors.

We have selected information of general interest to feature on these pages.

  • I-Gard and Industry Editorials
  • Power Problems & Solutions

Inside our Technical Library you will find our Product Guides and Manuals, Application Guides and Educational Information to keep you up-to-date on the latest thinking in the world of power protection problems and solutions.

Addressing Ground Faults
There are many options for grounding generators. This editorial discusses the advantages and disadvantages of each under a ground fault condition. Power continuity is essential in many industrial and commercial installations where a trip out due to ground fault can have serious economic and operational consequences.
EL Grounding of Standby Power Systems
An arcing phase to ground fault can pose a flash hazard to the maintenance worker close to the fault and can totally destroy the equipment. Consequential downtime adds to the economic loss. Four typical grounding methods for standby generators and emergency power systems are examined. The paper concludes that high resistance grounding provides the best power continuity, the best protection against arcing ground fault damage in low voltage distribution systems (up to 1000 V) and improves reliability along with availability of standby and emergency power systems.
IAEI News Arc Mitigation
This article provides three possible techniques for mitigation of electrical arc flash hazards: reducing the frequency of hazard, preventive action technology, and arc mitigation technology. With any hazard, there are different methods to define risk and its impact. Quite often the impact in business interruption far outweighs the physical damage to equipment. Industry statistics would suggest that the average physical equipment damage is about $50,000 and the business interruption cost is about $85,000 per incident.
IAEI News Grounding of Wind Power

Power continuity is essential in wind power projects where a ground fault leading to an interruption can have significant impact due to the logistical issues in servicing such large and often remote equipment.

Without effective ground fault and arc fault protection, arc faults within a wind powered generator can destroy expensive equipment impacting the economy and operations.

IAEI News Let's Get Serious About Electrical Safety

Despite awareness campaigns, industry statistics and loss summaries, annual safety conferences and numerous industry associations driving the safety message, we still take a reactive rather than proactive approach to electrical safety.

This editorial will outline the need for proactive and preventative measures versus the typical reactive protection measures often used today.

PCIC Total System Approach Paper
This paper provides a comprehensive discussion for the application and selection of various techniques and technologies available for the reduction and mitigation of arc fault hazards to personnel and equipment.
Resistance Grounding Booklet
Five chapters from Neutral Grounding Resistor Design to the use of HRG Technology in tackling the Arc Flash Hazard, combined with almost 200 application Q & A's, 'Ask The Experts' is a booklet with an excellent starting point for those looking to improve their product and application understanding of resistance and ground fault technology.
