HVDC converter - Wikipedia HVDC converter converts electric power from high voltage alternating current (AC) to high-voltage direct current (HVDC), or vice versa. HVDC is used as an alternative to AC for transmitting electrical energy over long distances or between AC power systems of different frequencies. HVDC converters capable of converting up to two gigawatts (GW) and with voltage ratings of up to 900 kilovolts ...

How to Detect Oil Leakage in Transformer - CR4 Discussion ...· 2. If transformer is small enough, clean as above and wrap the transformer with the absorbent pads. Any oil leak will show as an oil stain on the pads. 3. Put a full coverage (one pad thick) under the transformer. Pressure test. If there is an oil stain on the pads follow the path of the oil up from the soiled pad to the leak on the transformer.
