Standard Transformers
In
order to meet the growing demand of transformers with
short deliveries in domestic supply, TESLA have developed
a separate production system called TST (TESLA Standard
Transformers).
This range of TST are manufactured with
standard losses and in accordance to IS : 2026 latest.
TESLA can supply a comprehensive range as depicted below
in short delivery periods.
The second of our production system known as TESLA Repeats
transformers enables us to reproduce any of our previous
transformer designs again with the object of keeping
delivery time to a minimum.
Details of Characteristics & dimensions of TESLA standard
transformers with standard fittings manufactured in
accordance with IS : 2026 latest, and can be delivered
in short delivery period upon order confirmation.
SPECIFICATION
TESLA make outdoor type, 3 phase, 50 Hz, oil immersed,
conventional bolted ONAN cooled, Pole / Platform mounted,
double wound with Cu conductor, step up, core type continuous
duty transformers with + 2.5% to - 7.5% taps on HT side
for HT variation and leads to be brought out on off
circuit tap changing switch with locking device and
outside indicator arrangement and connected in delta/star
as per Vector group Dyn11.
The temperature rise will be 50/55° C in Oil/Winding respectively
over a maximum ambient temperature as per IS. The transformers
will be manufactured as per IS: 2026 latest, complete
with fittings/accessories as stated below.

- The
dimensions and weights shown above apply to a typical
range of TST (TESLA standard transformers) design
to the specification IS : 2026. As all transformers
are usually designed and built to customers' specification
their exact dimensions and weights can vary.
- Due to improvements continuously taking place in design,
the details given here may vary marginally irrespective
of Length, Width, Height, Oil and Total Weight . However
the variations will be within permissible tolerance
limits as per IS 2026 latest & IEC Standard.
