What is RTCC in a transfomer and specify its function.
Answer Posted / praveen
RTCC is Remote tap changer circuit, normaly RTCC panel will
be installed in Main panel room and will be connected to
OLTC ( On line tap changer) of the transformer through
control cable.There will be AVR in RTCC Panel to control
the secondary voltage of the transformer and AVR output
will control OLTC motor in Clock wise or Anty clock wise.
and also there will be selection in RTCC panel for Auto and
manual operation.

In a power conditoining unit (inverter) of a solar plant when we measure the d.c. current fed by different strings of solar plates to inverter, the current in the negative wire is less almost by 1 ampere to the current in its positive wire say current in positive wire 5 A , then current in negative wire of the same string is 4 A. Since the current entering should be equal to current leaving then why the current is noticably less in negative wire.
In 90 kva alternator that produce the output voltage is 115(p-n),200(p-p) at 1500 rpms means what ampere it produced ?
If we have to feed a housing complex having load 8MVA, than what would be the better option, either we first step down 33kv supply into 11kv & than 430v or we proposed no of 33/.44 kv transformer, also which option is economical?
I have 4 DG set with 1500KVA rating. system breakers are 11KV & alternator are 415 Volts. Between alternator & breaker one stepup transformer used. i want to Know what is max. resistance for body earthing & 415 & 11KV V Neuteal earthing. my fault current is 14 times for 2 sec.
for 11KV OH system what will be typical per KM "R" "L" "C" parameter. for 33KV OH system what will be typical per KM "R" "L" "C" parameter. for 33KV UG system what will be typical per KM "R" "L" "C" parameter.

This is reqd for a 1MW Solar power plant..We have 2DC outputs from the solar panels Connected to 2INVERTOR panels.. Output from invertor is 3ph,280v,500kva,50hz.These are connected to individual ACB.This has to be stepped up to 11KV ,1250KVA SYSTEM.Now can I use (1) one more ACBTO GIVE A COMBINED OUTPUT OF 1000KVA,280V & STEP UP THE OUTPUT BY USING a single two winding 3 ph transformer 11kv/1250kva. or (2)use the two outputs and connect to one three winding transformer of above rating..Pls suggestwith details.
