What is transformer tap changers please explain..

Answer / bharani

Transformers in general can have tappings in both primary
and secondary.
When we talk of HT transformers, tappings are provided in
the primary winding, this helps us in getting proper output
voltage by changing the tapping whenever the HT voltage
varies from the actual specified voltage.

What is transformer tap changers please explain..

Answer / byd

i am working at Transformer factory as test engineer, tap
changer is the part of transformer's primary winding which
is use to balance secondary voltage, for example we
have transformer which feature are: 630kva, 33/0,400 kv,
and this transformer has a tap changer , transformer
primary voltage positions are like these
HV(v) Lv (v)
28500
30000
31500
33000 ....... 400 v
34500
36000
network voltage is 33000v but sometimes it can be
increase or decrease , you can change tap changer:)
but this for no-load tap changer for distrubition
ransformer, if it is power transformer you should use
load tap changer
