Answer Posted / alleysyed
OLTC stands for On Load Tap Changer, which means that a user
can change the taps of transformer winding without
disconnecting the transfomrer from the supply. Taps are
changed in order to regulate the voltage. OLTC has number of
taps . They may be 10, 11, 16 , 20 or the customer specified
rating.
Marshalling box is a box in which manufacturer of
transformer bring alarm and trip contacts signalling from
the accessories associated with the transformer. For
example, Oil temperature indicator installed on the T/F
provide a signal of alarm when the temperature of oil
exceeds the specified limit of Indicator. If temperature
exceeds more, it send the trip signal to Marshalling box,
which disconnects the transformer from main supply and
vacuum Circuit Breaker is tripped. VCB is installed on the
High Voltage side of the TF in the HV Protection panel.
