5.3. LOWΩ – SETTINGS FOR CONTINUITY TEST WITH 200MA
The purpose of this measurement is to test the continuity of protective conductors and
equipotential ones (e.g. from rod to earth and connected foreign earth) and earth rods of
SPDs on PV installations. The test must be carried out using a test current > 200mA
according to the prescriptions of IEC/EN62446 guideline
