Distribution auto-transformer / high-power - 200 MVA

These are large power transformers which are made by the Siemens company. They have a power range that is greater than 200 MVA. The transformers have on-load or off-load tap chargers. Some models may even have both types.

Based on the onsite needs, these transformers can be designed as either autotransformers or power transformers that are multi-winding. Autotransformer styles come in 1-phase and 3-phase versions. There are models that come with ratings greater than 1,000 MVA and voltages measuring up to 765 kV (800 kV).

As customers can see, the limits of what is feasible have not yet been reached by our company. All power transformers are made in accordance with both national and international standards. IEC 60076, ANSI, and IEEE requirements are all met by these devices.

Current transformer / closed-loop / toroidal - DER3B

The Dossena toroidal current transducer B series, can be used in conjunction with the earth differential relays DER3B and transducers series D, to allow and to detect homopolar/differential currents to the ground. The transducers have to be installed upstream of the line or load to be protected and monitored, and all conductors (phase and neutral) of single-phase or three phase must be passed inside the transducer.

Open loop transformer / current / toroidal - DER3

Open loop transformer / current / toroidal - DER3

The torodial transducer series D should be used in combination with earth differential relays DER3, as it allows the unit to detect and locate homopolar/differential current. These unit is equipped with normal winding leaking current measurements, in addition to a winding test. Buyers should note that the transducers must be installed upstream of the line or load to ensure that they are protected and monitored.

If done correctly, all conductors, phase and neutral of single-phase or three-phase will be forced to pass through the transducer, and Dossena employs a special magnetic alloy so that the ferromagnetic core ensures wide magnetic quality whilst also detect the most minute current values. There is a wide range of transducers to choose from, so buyers will be able to find one to suit their needs.

Safety transformer / single-phase - 230 V | TR 26 H

Single-phase safety transformers intended to supply spotlights in swimming-pools, garden ponds, ornamental fountains and moist locations, where for safety reasons it is necessary to supply with safety extra low voltage (SELV). It has several taps in the primary winding in order to compensate for the voltage drop in the transformer-spotlight line conductors and thus gets an adequate brightness in every spotlight. On request we can manufacture transformers with other rated power or voltages, or with other line lengths between transformers and spotlights. The main characteristic of this model is the reduced height that allows the installation in a low profile box.
