The basis for safe electrical systems during operation

The standard DIN VDE 0105-100 sets out the safety requirements for the Operation, testing and maintenance of electrical systems firmly.
It applies to all voltage ranges and affects operators of building services, industrial plants, public institutions and commercial electricity consumers.

What does DIN VDE 0105-100 regulate?

The standard describes measures to ensure that electrical systems are operated:
To prevent accidents involving electrical current
To protect employees and third parties
To ensure plant availability
to comply with legal requirements
It contains requirements for:
Safe operation and shutdown of systems
Initial examination & repeat examination
Labeling & protective measures
Responsibilities & Documentation

To which systems does this standard apply?

Main distributions & sub-distributions
Lighting & security systems
Industrial & production facilities
Building services in administrative and school buildings
Facilities in care and healthcare facilities
Emergency power systems & UPS systems
💡 This standard also applies to work on or near electrical installations.

Tests according to DIN VDE 0105-100

Visual inspection of the system for defects and hazards
Insulation and protective conductor testing
Loop impedance and voltage measurement
Checking protective devices (e.g. RCDs, fuses)
Documentation including test report & evaluation

How often should I check?

The inspection intervals depend on the risk assessment – the following are common:
All 4 years for stationary installations (office, school, etc.)
Annually to semi-annually in sensitive areas (e.g. clinics, nursing homes)
After modifications or repairs: immediate retest

Advantages of testing according to VDE 0105-100

Legally compliant operation of the entire electrical system
Early detection of defects and weak points
Evidence security in cases of damage or inspections
Basis for risk assessment and maintenance planning
