Service Characteristics
A full technical audit of the electrical installations includes, among others, assessment of the following aspects:
- Compliance of the installation with the corresponding single-line diagram.
- Efficiency of the protection against both direct and indirect contacts.
- Suitability of components to environmental conditions (moisture, dust, presence of water, etc)
- The correct use and type of electrical conductor protection.
- The correct size of electric spreaders, earth conductors, and all other protection–related items.
