Brigstowe Electrical Services Ltd are qualified to conduct all DNO witness tests on all renewable energy sources where a G59/3-1 relay is required (i.e. hydro, wind turbine, biomass, solar PV, generators etc.)
G59/3-1 testing has to be completed by a qualified engineer and the DNOs have a duty to ensure that where embedded generation is connected to their network; G59/3-1 parameters are complied with.
Companies can face large penalties if they fail to follow the G59/3-1 requirements. All manufacturers G59/3-1 relay set ups are different.
The G59/3-1 tests need to take place on the client’s site as the nominal voltage will be site specific and the parameters for the above tests will be set according to that nominal voltage.
G59/3-1 Relay Testing is also known as the G59 Test and must also be carried out by a G59 tester.
After each test we will issue a test sheet signed by our test engineers and the DNO protection engineer (if needed).
The sheet contains details required by the DNO according to Engineering Recommendation G59/3.
