Distance relay lockout on weak end indeed.

[amtprot]

Distance relay didn't Autoreclose (1P) on weak end due to non sensing of C- Phase (ABC phase) fault 16000Amp.on 10 Km long 220 KV line by distance feature Micom P443 relay but IDMT Earth fault feature operated in 900mSec resulting in lockout before dead time of 1P AR 1 Sec.Although source end tripped 1Pole and reclosed correctly but weak end got lockout on Earth fault IDMT.The current contribution at weak end during dead time of source end AR cycle was A phase 500A,B phase 950 A and C phase 510 A and Neutral 2000Amp.At weak end there were two 100 MVA 220/66 Kv transformers connected on 200 KV bus.
I don't want to increase IDMT Earth fault TMS and I want that my AR cycle on source end gets completed before weak end lockout by Earth fault relay.How could I avoid E/F trip on weak end.
Cfg file and event file attached.

Further data on the fault is
CT ratio 800/1 A ,.
Single pole Auto reclose setting enabled.
SP AR Dead time 1 Sec.

Directional E/F I> 0.2 A, TMS 0.3 IDMT.
Issue is that I didn't want any lockout on weak end.Either distance should trip on aided scheme PUR which didn't sense the fault thus Directional IDMT E/F operated and my supply effected.Apart from the above 2000Amps. in neutral of line was due to transformer star/Star solid grounding providing return path from weak end line side to fault point through earth ?
