RTCC means relay tap changer circuit,these are the relays
which give command to the tap changer present in the
transformer H.T side to either increse or decrese the tap
since due to inductive load ( lagging p.f ) , the secondary
terminal voltage would decrease which would not be good for
the loads so by chnging taps, we increase the primary
voltage which in turn changes the secondary
voltage,normally done online.
RTCC panel is called as the Remote Tap Changer Circuit. it
is used to control the OLTC Tap changer from the control
room or control point itself where RTCC panel is Placed. it
is used to get the stable output voltage.
RTCC MEANS REMOTE TAP CHANGING CIRCUIT. AND REQUIRED FOR
CHANGING THE TAP AT THE HV SIDE OF THE TRANSFORMER ONLINE
IF THE LV SIDE VOLTAGE OF THE TRANSFORMER FLUCTUATE
BEACAUSE OF LOAD. IT HAS AVR (AUTOMATIC VOLTAGE REGULATOR)
TO CONTROL THE TAP CHANGING.
It stands for Remote Tap Changing Controller.This is used
to maintain Constant voltage at the secondary side of the
Transformer i.e at the load side by suitably changing the
tap positions at the primary side automatically.
It really is a boon to power industry as the load varies
heavily which is largely inductive so the power factor &
voltage is to be maintained,which is possible using this
It is also known as Automatic Voltage Regulator.
i need to connect fact device(any one from following
upsc,sssc,svc,statcom and tcsc)in 14 bus system....by using
MATLAB psat software....if i connect these fact devices,i
will get some error as "virtual error"...i cnt rectify this
error.if anybody know that how to work in psat,pls help me
to rectify this error....
or send mail me to,
