TTI series is made of transformers whose primary and secondary coils are electrically separated through ane lectrostatic screen in order to reduce any danger due to a simultaneous accidental contact between earth and metallic parts that could go under tension in case of a breakdown of the insulation.
The connection of phases is usually possible as star. In request the dimensions can be changed in order to fulfil any volume requirement.
| Technical specifications: |
| – insulation class E – frequency 50/60 Hz. – open execution, protection level IP00 – ambient temperature 40°C – either vertical or horizontal execution – resin impregnated and tropicalised – vectorial group Yy0 – other vectorial groups on request – electric class of protection l – screen between primary and secondary |
