Each configuration gives different testing opportunities. For island-mode sets, the implications of being unable to test in parallel with the DNO should be considered: unsupported circuits may have to be turned off during on-load tests, so load bank testing is the alternative, and tests and mains restoration will need a short break unless a no-break return is designed in. Parallel operation with the PES must comply with ENA G59/3-2: short-term parallel (1 to 5 minutes, with DNO approval) allows a no-break return to mains; long-term parallel allows testing on the real supported load without any break. Best practice is to allow long-term parallel operation; where generators can parallel with the PES, neutral-earth switching contactors should be included. Parallel operation is acceptable for all risk categories provided high-risk areas have an intermediate UPS. Sets above 20 kV or 5 MW should comply with G.75/1.
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
