Clear safety standards for new low-voltage grids

New low-voltage grids must comply with carefully specified safety standards. This has been laid down in a decision that the Netherlands Authority for Consumers and Markets (ACM) has published. This decision contains the safety standards that grid operators need to apply when designing and operating new low-voltage grids.

Many low-voltage grids are connected to devices such as lampposts, traffic light installations, and billboards. Henk Don, Member of the Board of ACM, explains: “We also make sure that power is transmitted safely. Short circuits in low-voltage grids cannot lead to dangerous situations for citizens. This new decision offers clarity regarding the standards that new grids need to comply with.”

ACM sets stricter safety standards for new low-voltage grids than the system operators had collectively proposed. The differences concern risk areas such as parks, playgrounds, and recreational areas. These are locations where people often walk barefoot. They are particularly vulnerable if they touch or step on live objects. For these areas, ACM uses a maximum step and touch voltage of 25 Volt, whereas system operators had suggested 50 Volt.

For existing low-voltage grids, ACM will set concrete safety standards in 2018.
