New article by a trained electrical engineer from Venezuela. Enjoy!

When dealing with electrical installations, you must be aware of some special scenarios that could come across, which require particular considerations in order to make a safe and reliable design for equipment and more important yet, for people’s lives.

These scenarios constitute restricted areas for most people, special places in which careful measures must be taken to enter in them, whether exists the possibility of explosion or fire due to a mixture of particular elements like a surge of energy, sparks or arcs produced by the flow of electrical energy.

An electrical insulation is a material that reduces or prevents the passage of electricity from one conductor to another due to its high level of electrical resistance. Let’s read Ginnie’s essay about electrical insulation failure.

The main purpose of insulation is to prevent any electrical shocks and reduce the possibility of any kind of electrical failures, making of is one of the most necessary aspects to take into account in the industry of electricity.

The reasons why insulation fails vary depending on the type of material and the element to be insulated. The following provides a description of the main reasons for insulation failure:
