Value
Depending on the frequency of the voltage measured: f
±0.5% or ±0.002 x I
n
(at currents in the range of 0.01 to 4.00 x I
Note: The protection and control relay may indicate non-zero phase current measurements in the
range of 0.003...0.01 x In when the recloser is in the open state.
DFT: -50dB at f = n x f , where n = 2, 3, 4, 5,...
