Products Advantage

Oil-immersed Power Transformers from KanmPa are specified with multiple rated voltage and nominal voltage combinations, enabling alignment with medium-voltage power systems. Electrical parameters include continuous operating voltage, DC reference voltage, and maximum leakage current limits, supporting predictable insulation and operating behavior. The category is characterized by quantified impulse current handling, including steep wave shock current, lightning impulse current, and 4/10 μs peak impulse current ratings. These parameters support application scenarios where defined transient performance and controlled residual voltage levels are required within power distribution networks.

What are Oil-immersed Power Transformers?

Oil-immersed Power Transformers are electrical devices designed for voltage transformation in power systems, using insulating oil to manage insulation and thermal performance under rated electrical conditions.

How are rated voltage and nominal voltage different?

Rated voltage defines the maximum design voltage of Oil-immersed Power Transformers, while nominal voltage represents the standard system voltage level for which the equipment is intended.

How should continuous operating voltage be interpreted?

Continuous operating voltage indicates the voltage level that Oil-immersed Power Transformers can withstand during long-term operation without exceeding specified electrical limits.

Which parameters describe impulse current performance?

Impulse current performance is described through steep wave shock current, lightning impulse current, operating shock current, and 4/10 μs peak impulse current ratings.

How is leakage current evaluated in Oil-immersed Power Transformers?

Leakage current is evaluated at a defined percentage of the DC reference voltage, providing a measurable indicator of insulation behavior under controlled test conditions.
