A system for detecting leaks in a hydraulic supply system for a double-acting hydraulic actuator is disclosed. The system may include a first conduit in fluid communication with a first chamber of the actuator, and with a second chamber of the actuator, and a directional control valve coupled with the first conduit and the second conduit. A directional control valve may be in fluid communication with a hydraulic oil supply line and may switch between the hydraulic oil being sent and received via the first conduit and second conduit. A valve can be associated with the oil supply line. A first and second flow meter can generate a first signal and a second signal, respectively, indicating flow rate within the first conduit and the second conduit. A controller may receive the first signal and the second signal, calculate their ratio, and cause the valve to inhibit flow within the oil supply line upon the ratio differing from a given ratio by more than a predetermined threshold.
