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.

Answer / xyz

RTCC means- Remote tap changing controler and it is used to
maintain the stable output voltage of the transformer by
changing the taps because we need costant voltage then only
rtcc is required

Answer / rashid abdul rab

RTCC panel also known as AVC Panel (Automatic Voltage
Control Panel), is used to control the Transformer tap
Changer to adjust the tap position, as per the load

Answer / shiva sharana

RTTC MEANS REMOTE TAP CHANGING CONTROL IT IS USED TO
COMMAND THE OLTC PANEL CONTROL THE PRIMARY SIDE OF
TRANSFOMER . WHEN WE REQUIRD CONSTANT VOLTAGE IT IS REQUIRED

Answer / dipak patil

RTCC stands for "Remote Tap Changer Control". RTCC panel
is used to give operation command to OLTC(On Load Tap
Changer)of Power Transformer from remote end.

Answer / bala

Dear V.Senthil
your statment is correct but the OLTC provide on HT side
only .

Answer / bala

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.

Answer / chetan

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.

Answer / ajinkya a. avinashe

Rtcc is remote tap changer circuit. It is used to change tap position as per requirement of load. It generally maintains voltage at specific value, if there is any change in voltage rtcc gets it at reqd value.

Answer / b.c.pandey

RTCC means REMOTE TYPE TAP CHANGING CONTROL panel,it is
used in transformer for tap changing.It contains an AVR
(Automatic voltage regulator),Relays and contactor for
motor.

why we are used D.c. voltage in L.T.side or controling side.we can use UPS also ,in place d.c. voltage
