Andrew Cochran

Andrew Cochran is the president of I-Gard, a company that provides technical support in the application of ground-fault protection and resistance grounding products. He has been with I-Gard twelve years, having spent time in an operations capacity previously with Polariod, Stanley and ITT. He was educated in the UK in manufacturing and production engineering.


Responsible Electrical Safety

The use of electricity has inherent risks, particularly electric shock and arc flash hazard. However management tools and technology are readily available to mitigate and manage these risks.

Electrical Safety — It is Time to Get Serious!

Despite awareness campaigns, industry statistics and loss summaries, annual safety conferences and numerous industry associations driving the safety message, we still more often than not take a reactive rather than proactive approach to electrical safety.

Arc Mitigation – A Three-Step Approach

With any hazard there is a definable risk and a definable impact and it is no different for the arc-flash hazard. Quite often the impact in business interruption far outweighs the physical damage to equipment and industry statistics would suggest that the average physical equipment damage is around $50,000 and the business interruption cost around $85,000 per incident.

Using Technology to Minimize the Arc-Flash Hazard

Although arc hazards have existed since man began using electricity, increasing deaths, injuries and property loss from arcing faults have led to increased awareness of the issue and investigation into methods of protection.

Using Technology to Reduce Risk and Improve Worker Safety

Empirical data indicates that around 80 percent of all electrical interruptions are attributable to ground faults that are a result of an unintentional connection between system conductors and ground. The term grounding is commonly used in the electrical industry to mean both "”equipment grounding”" and "system grounding.” System grounding means the intentional connection of a neutral or phase conductor, either solidly or through an impedance or resistance device, to ground from a source such as transformer, rotating machinery, solar photovoltaic, etc.
