Special transformers designed entirely according to customer needs, used in the private applications and projects of companies, at various voltage levels or different frequencies.

Grounding Transformers

Grounding transformers are designed to create an artificial neutral point in ungrounded three-phase power systems. During phase-to-ground faults, grounding transformers provide a safe path for fault currents to flow and limit transient overvoltage fluctuations. Grounding transformers are expected to carry the short-circuit ground current until the circuit breaker clears the fault, hence they have a rated capacity suitable for short-term operation. The rated (kVA) capacity of a grounding transformer varies depending on the normal phase-to-neutral voltage and the magnitude of the fault current within the specified time interval (ranging from seconds to minutes).

Railway Transformers

Railway transformers are special electrical converters used in railway transportation systems. These transformers are specifically designed to convert high-voltage energy from electrified railway lines into lower voltage and higher current needed by trains. Railway transformers serve various purposes such as powering trains, energizing signal systems, and providing electricity to other railway facilities. Their reliability and durability are critically important for railway operations.

Phase Shifting Converter Transformers

These transformers are tasked with isolating the system from the grid and reducing harmonics generated by the converter unit by adjusting the number of phases as required.
