Figure 1-2. Current Sensing Input Burden (BE1-50/51B-244)
Frequency Response
A change of ±5 Hz from the nominal 50/60 Hz current causes <0.5% change in the current required for
pickup.
Transient Response
<10% overreach with system time constants up to 40 ms.
Harmonic Rejection
Rejection of odd and even harmonics is illustrated in Figure 1-3.
