Magnetic Oil Level Gauges (MOG) are essential instruments used in oil-filled power transformers to monitor the level of insulating oil in the conservator tank. These gauges operate using a magnetic coupling mechanism that transfers float movement inside the tank to an external dial indicator without mechanical penetration, ensuring leak-free operation. Magnetic Oil Level Gauges provide clear oil level indication and may include alarm contacts for low oil level warning. They are widely used in electrical substations, power plants, and industrial power systems to maintain safe transformer operat
