Setting of ik

ik determines minimum operation sensitivity of DIF element. ik is set as a ratio to the CT
secondary rated current.

Minimum setting of ik is determined from the maximum erroneous differential current under
normal operating conditions.

Setting of p1, p2 and kp

Percentage restraining factor (% slope)

= (Differential current) / (Through current)

= (Differential current) / [{(Incoming current) + (Outgoing current)} /2]

p1 is the percentage restraining factor which defines the DIF restraining characteristic in the
small current region. The setting is determined by the sum of:
