Three Phase

Three phase transformers can be used to step voltages up or down and to provide galvanic isolation. They can be categorised as Auto transformers and Isolation transformers. Tortech manufactures 3 phase and 1 phase transformers up to 2.5MVA and 33kV in rating. These transformers can be supplied as open or encased units.

 

 

DRY TYPE ISOLATION TRANSFORMERS:

UP TO 500kVA and 1kV

Isolation transformers can be used to provide galvanic isolation between input

and output windings.These transformers can be built with an interwinding earth screen.

This screen is effective in attenuating common mode noise present in the supply.

Isolation transformers  are commonly used for testing, centralised grid connected 

PV inverter(MV Split winding transformer),UPS isolation, Railway and Defence applications.

All dry type transformers are routine tested to AS 60076.11. Special type tests such as 

temperature rise and impulse tests can also be prepared. Isolation transformers can be

used to provide galvanic isolation between input and output windings. These transformers

 3 Phase Isolation transformer - Dry type


RESIN CAST TRANSFORMERS:

UPTO 3.5MVA AND 33kV

Resin Cast Isolation transformers can be used in installations which require

a Fire rating class of F1. The transformers are designed to operate under natural

convection of air. They can also be manufactured with a cross flow fan for controlled

by the temperature controller for forced cooling to allow operation under extreme

Australian conditions. Resin cast transformer range is commonly used for Photovoltaic

grid systems, Railway and UPS isolation systems. The transformers are routine tested

for partial discharge <10pC and can also be impulse tested up to 400kV.

 3 Phase Resin Cast transformer

OIL COOLED TRANSFORMERS:

UP TO 3.5MVA AND 33kV

This transformer is an energy saving and hermetically closed oil-filled transformer

which is produced by winding a core made of nano-crystalline amorphous glass

metal ribbon. This transformer is ideal for large PV plants that work with several

central inverters which feed with maximum system yield to the medium voltage grid.

Upon request the transformer can be designed with a maximum of four low voltage windings.

The vector group Dyn5yn5 then increases up to a maximum of Dyn5yn5yn5yn5.
