I would much more appreciate to support me regarding find tools acceptable for safe installation and dismantle of glands.
Please send details of manufacture.
Thank you in advance
but it is not my main subject i would like to now could i connect portable ups to auxiliary socket, and elements in circuit will be several contactors and one or two fan motors 0.45kW, purpose is to keep running cooling fan in case of main power failure.
During normal operation fan cooling the resistance elements which are energized and it is in manual that for normal stop of load bank set load bank to ''0'' it will de-energize all resistance elements and run cooling fan for 10 minutes and then fully isolate.
but it is not my main subject i...
If load bank main power to resistance and auxiliary to control circuit comes from one source for example main generator and in case of generator trip with fail to start stand by load bank will overheat because cooling fan stop.
Could you please advise regarding auxiliary power for load bank? Could it be used UPS system with suitable output power for that, there will be contactors and cooling fan with maximum load 7-10amps.

Thanks Elena and what do you think could reason of CT damage?
Existing current transformer manufacture ‘’Frer’’ type TA0008800K01 Ratio 800/1 A 0.72-3kV 5P15 M0503 resistance secondary winding 11 Ω but failed CT was 5.6Ω
Generator is 350 KVA and usual load about 50% but recently disbalance appeared probably because load bank failure, we observed difference in phase current and it were about LI-200A L2-200A and L3-100A and burned transformer was on phase L3 reviled it later after ACB trip by multifunctional relay.
