Client:
Taurus-Technic Sp. z o.o.
A national leader in the field of reactive power compensation (LV and MV) and a licensed partner of SIEMENS, a world leading company in the market of electricity distribution. On the Polish market since 1991. Taurus-Technic also offers the latest solutions of LV switchgears and a whole range of MV switchgears.

The Challenge:
The required compensation power of 900kVAr with the possibility of its gradation (2 x 450kVAr) and very limited space for installation compared to standard solutions.

The Solution:
A unique solution designed specifically for the Partner's needs, with two independent reactors placed one above the other. Reactors of this type are usually used in wind farms to compensate the reactive power resulting from the capacity of the supply lines.

Results:
The compensation reactor type ED3KH-2x450 is one of two double compensation reactors with a power of 900kVAr (2x450kVAr) and a rated voltage of 15.75kV. ED3KH-2x series reactors have a common yoke, which reduces the amount of materials used for their construction (compared to two separate, independent reactors), giving economic benefits and making the most of the available space.

Client:
Praxis Automation Technology B.V. develops and manufactures ship automation and electric propulsion systems for all types of vessels. With all applied products of the automation and electric propulsion systems developed and manufactured in-house, Praxis offers a unique package which requires little to no system integration work. This approach is unique on the market and ensures unsurpassed cost efficiency and safety.

The Challenge:
Praxis is a leader in supplying electrical systems for fast motor yachts. Market trend is to minimize the weight and dimensions of all ship equipment. That forces the manufacturers to look for the most optimized solutions. Products need to be small and light, while keeping top performance and high reliability.

The Solution:
Elhand offered individual, compact design of an LC filter and a transformer in a common enclosure. To reduce the weight, both the windings and the enclosure were made of aluminum. The other goal was to minimize the footprint, which was achieved by implementation of a water cooling system. The customer received a dedicated product, which was easy to integrate with the yacht’s electrical system.

Results:
GRID CONVERTER'S OUTPUT SET is a ready-made solution, which enables connection of a grid converter to the ship utility grid. Frequency converter’s output voltage is transformed from PWM to sinusoidal waveform thanks to the sine-wave LC filter. Then the transformer eliminates common-mode voltage and adjusts its value to the customer’s requirements. The grid converter together with Elhand components create sinusoidal, galvanically isolated and stable voltage supply.
