1.10 Earth Fault Wattmetric protection test
The earth fault wattmetric protection can be tested but as above needs of the residual
voltage injection the wattmetric power is calculated as Ie x Ue x cos (Ie^Ue+
ϕ
c)
The calculation is referred to the secondary values.
The same test can be repeated for the second stage.
Type and setting Pe stage are in
watt referred to the secondary.
The setting value depends on the
set nominal Ien current (1A). Value
