and current measurement I .
The frequency response of the equipment can be set for a linear frequency re-
sponse (up to the maximum frequency of 2000 Hz) if used for fire protection
or for a frequency response in accordance with IEC 60990 for personnel pro-
tection. For plant protection, the residual current is measured up to the rated
system frequency. The figure below shows the corresponding frequency re-
sponse.
Param. Objective
50 Hz Plant protection: Only evaluates the fundamental compo-
nent of the current measurement.
60 Hz Plant protection: Only evaluates the fundamental compo-
nent of the current measurement.
IEC Frequency response acc. to IEC 60990: Above 200 Hz
(approx.), the set response value increases according to the
hazard curve in IEC 60990.
None Fire protection: Response factor remains the same over the
entire frequency range.
