Abstract: An instantaneous separation system for capturing and recovering oil from an outdoor electrical equipment. The system includes a capture system for capturing a mixture of oil and water and transporting the mixture to an instantaneous separation reservoir. The separation reservoir maintains the separated oil and water separate via a separation plate. A water outlet pipe transports the separated water back to the surroundings, an oil outlet pipe transports the separated oil to an oil reservoir; a nominal water level threshold maintains the separated water at a given water height by directing any water surpassing the water height to the surroundings via the water outlet pipe. The nominal water level threshold and the separation plate ensure that substantially only the separated water enters the water outlet pipe. An oil outlet threshold is positioned at a height that is greater than the height of the nominal water level threshold.
