Circuit breakers are essential for protecting the substation and the wider power distribution network from overloads and short circuits. They work by automatically interrupting the electrical flow in the event of a fault, thereby preventing damage to equipment and ensuring safety. Modern substations may employ various types of circuit breakers, such as air-insulated, gas-insulated, or oil-filled breakers, each offering specific advantages depending on the operating environment and design considerations.

2. Oil Filters The oil filter removes contaminants from the engine oil, including dirt, metal particles, and sludge. Clean oil is vital for lubricating engine parts, reducing friction, and dissipating heat. A functioning oil filter helps maintain the oil's cleanliness and prolongs its service life. If the oil filter becomes clogged, it can restrict oil flow, leading to engine wear and potential failure. Regular oil changes and filter replacements are critical for engine health.
