LSND

The program is used for execution of calculation part of designing the general purpose transformers, operating at 50 and 60 Hz.
General purpose for single-phase power transformers:
– with plane-laminated magnetic system comprising one leg and two side yokes;
– with plane-laminated magnetic system comprising two legs and two side yokes,
– with one compensating winding on one of the side yokes;
– with plane-laminated magnetic system comprising two legs without side yokes.

General purpose for three-phase power transformers:
– with leg plane-laminated magnetic system;
– with five-leg plane-laminated magnetic system.

The possibility of calculation of transformers with different cooling systems is taken into account, calculation shall be made in the range of the leg rated induction 1.2 – 1.8T.

1 – Transformer tank projection to the horizontal plane.
2 – Projection of the cooler to the horizontal plane.
3 – Projection of measuring surface S03 measured at distance of 0.3 m from projection of the noise source.
4 – Is the projection of measuring surface S20 measured at the distance of 2.0 m from the noise source projection.
