All countries in the world have special regulations for testing and approvals of low voltage installations. In many countries these regulations are prescribing installers, inspectors etc. to check the electrical installation periodically.
The basis for the local regulations is in many occasions the IEC/EN 60364 “Electrical installations of Buildings”. In relation to this regulation, all important parts of a LV-installation need to be approved.
Prescribed tests that need to be performed are:
- RCD test
- Insulation resistance test
- Earth loop impedance test
- Earth loop resistance test (Rs-test)
- Earth resistance test
Obviously, values such as voltage and frequency are part of every test as well. Secondly, the regulation EN 50110 “Operation of electrical installations” is translated and formed to many national regulations. This regulation is specifically for operation or maintenance of low voltage installations and distribution systems. These installations are mostly in housings, factories or office buildings.
Besides the regulations, the growing number of ‘aging’ installations as well as the increased product liability are important reasons to test all parts of installations thoroughly.
In order to test all necessary components of any installation and to perform all tests within the regulations, Nieaf-Smitt is offering several installation testers. There are individual testers for parts of the regulation and four combination testers.
