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 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
According to primary voltage variation, the RTCC gives
command to the on load tap changer which is provided in
transformer L.T side (i.e consumer side) to either increse
or decrese the L.T voltage to optain normal working voltage
to the consumer.
Tap changer should connect only in transformer consumer
side. Because the HT side line connected with main grid. So
we can not change the grid voltage.
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
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
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.
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.
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.
1.What is effect of capitance in transmission line?
2. After raising the voltage at receiving end what will
be happen?
3.how we nullify or control the raised voltage at
receiving end?
3 ph motor connected in star delta starter. when we start
the motor it run in star but when in is going in delta it
trips the main incoming supply. why?
how to calculate Amp, 2 different Amp of batteries?
Example:
No. of Batteries = 2
Battery voltage = 12V
1st Battery rating = 17AH
2nd battery rating = 30AH
between parallel connection then output volt
12v
Amp?
