Answer
# 1
RTCC is a panel it should be place in the electrical room
for Remote Tap changing.It must Required while OLTC is used.

Answer
# 2
RTCC is Remote Tap Change Circuit is connected to OLTC of
Transformer through control cables. It raise & lower the
voltage as accordingly specified by controlling the motor
drive in OLTC electrically (and manually through Push
Buttons)
In RTCC an AVR (Automatic Voltage Regulator)is fixed to
maintain the output voltage level(raise & lower) by
controlling the motor.

Answer
# 3
RTCC is " Remote Tap Change Centre " which is a
programmable device to control the output of the transfomer
thro'OLTC unit fitted in the transformer through control
cables.
The desired voltage will be achieved accordingly by
controlling the OLTC with respect to the tap position
through RTCC system.
The output voltage of the transformer is been maintained
through an inbuilt AVR (Automatic Voltage Regulator),which
continuously verifies the output power with the set /
programmed reference voltage.Which triggers the OLTC
accordingly.
Hence,by above said phenomena,the consistency of the
transformer output is been maintained.

Answer
# 4
In transformers Output Voltage can be controlled either by
Off Circuit Tap Changer (Manual tap changing)or By On -
Load Tap Changer-OLTC (Automatic Changing).

In the transformer with OLTC, it is a closed loop system,
with follwing components:

#1. AVR (Automatic Volatge Regulator- an electronic
programable device). With this AVR we can set the Output
Voltage of the transformers. The Output Voltage of the
transformer is fed into the AVR through the LT Panel. The
AVR Compares the SET voltage & the Output Voltage and gives
the error signal, if any, to the OLTC through the RTCC
Panel for tap changing. This AVR is mounted in the RTCC.

#2. RTCC (Remote Tap Changing Cubicle):This is a panel
consisting of the AVR, Dispaly for Tap Position, Voltage,
LEDs for Raise & Lower of Taps relays, Selector Switches
for Auto Manual Selection... In AUTO MODE the voltage is
contrlled by the AVR. I manual Mode the operator can
Increase / decrease the voltage by changing the Taps
maually through the Push Button in the RTCC.

#3. OLTC is mounted on the transfomer. It consits of a
motor, controlled by the RTCC, which changes the Taps in
the transformers.

Answer
# 6
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.

  Re: What is RTCC in a transfomer and specify its function.
Answer
# 8
RTCC IS REMOTE TAP CHANGE CUBICLE , WHICH GOVERNS THE
VOLTAGE CONTROL OF THE TRANSFORMER THROUGH AVR OR BY MANUALLY.

IT HAS ANNUNCIATOR (MICROPROCESSOR BASED PROGRAMMING)WHICH
ALARMS THE OPERATOR DURING THE FAILURE OF FAN ETC.
