Figure 1-3. Burden Characteristics
Frequency Response
A change of ±5 Hz from the nominal 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 Response
Figure 1-4 shows that a relay set for 1 ampere pickup would pick up at 0.96 amperes with a current
containing 40% seventh harmonic. This corresponds to a 10:1 rejection ratio. Other conditions may be
evaluated in the same manner.
