4. Differential protection
Restricted earth fault protection REFPDIF
1Ph High impedance differential protection HZPDIF
(87)
M13071-3 v8
The 1Ph High impedance differential protection (HZPDIF,
87) function can be used when the involved CTs have the
same turns ratio and similar magnetizing characteristics.
It utilizes an external summation of the currents in the
interconnected CTs, a series resistor, and a voltage
dependent resistor which are mounted externally
connected to the IED.
Three instances of 1Ph High impedance differential
protection function (HZPDIF, 87) can be used to provide a
three phase differential protection function to be used for
example as busbar protection. One instance of HZPDIF
(87) can also be used as high impedance REF protection.
5. Current protection
Four step phase overcurrent protection OC4PTOC
(51/67)
M12846-3 v9
The four step phase overcurrent protection function
OC4PTOC (51/67) has independent inverse time delay
