Static Frequency Inverters for High Voltage Cables and Large Power Transformers

High voltage cables for energy transfer as well as large power transformers of up to 1300 MVA must be tested by the producer in different ways. For this purpose, AC voltages with different frequencies are required.
In case of cable tests, these are lower frequencies (<10 Hz) due to bigger capacities, in case of transformers these frequencies can increase up to 200 Hz.

We have designed suitable electronical control systems and inverters for various customer projects. The software interface or an HMI can also be individually adapted according to your needs.
