Transformers: Reliable Power Supply and Protection for Your Industrial Equipment

Stable voltage and the safe operation of electrical networks are the foundation of any production process. Whether it is powering heavy-duty machine tools, operating measuring instruments, or organizing safe lighting in a workshop, reliable electrical energy conversion is indispensable. And industrial transformers play the primary role in this process.

In the " Dniprovskyi Electrotechnical Plant " online store, you can buy transformers of all popular types and capacities. We supply certified electrical equipment that will ensure the uninterrupted operation of your distribution boards, automation systems, and power units.

What types of transformers do we offer?

Our catalog covers solutions for both global power engineering tasks and local control circuits. Here you will find:

• Power step-down transformers (single-phase and three-phase): classic models such as OSM, TZI, NTS series, etc. They are indispensable for powering local lighting circuits, automation, starters, as well as for connecting imported equipment that requires non-standard voltage (e.g., 110V, 220V, or 36V from an industrial 380V network).
• Current transformers (CT): measuring devices necessary for the safe connection of ammeters, electricity meters, and protection relays. They proportionally convert high alternating currents into safe values (usually 5A), isolating the measuring equipment from high voltage.
• Voltage transformers (VT/PT): used for galvanic isolation, personnel protection, and accurate signal transmission in relay protection and metering circuits.
• Isolation transformers: provide maximum electrical safety in rooms with high humidity or an abundance of metal structures, preventing the risk of electric shock.

How to choose an industrial transformer?

When buying a transformer, knowing just the primary and secondary voltage is not enough. For the equipment to last long and not overheat, it is important to consider:

1. Nominal power (kVA): always include a 15-20% margin from the total power of the connected load to avoid overloads during inrush currents.
2. Number of phases: single-phase (220V) or three-phase (380V).
3. Operating conditions: enclosure protection rating (IP) and climatic version (for operation in dry electrical switchboards, outdoors, or in dusty workshops).
4. Accuracy class (for CTs and VTs): a critically important parameter for commercial electricity metering (0.2S, 0.5S).
