Safety is probably the biggest challenge with an electrical system. To ensure safety, electrical equipment must be inspected with appropriate testing and measuring procedures after installation, extensions and at certain intervals.
The requirements for such an inspection can be found in DIN VDE standards, particularly in DIN VDE 0100-600.
A full inspection by an electrical expert covers the following points:
- Visual inspection of electrical installations
- Metrological inspection of all circuits
- Testing of the system
- Documentation of the recorded values and system conditions
