The advantages of 2-cycle engines are evident in terms of size, weight, and power delivery. They produce strong power outputs and can operate in any orientation, making them versatile for diverse applications. However, there are trade-offs. One significant drawback is fuel efficiency; 2-cycle engines tend to consume more fuel since they often do not use a dedicated lubrication system, leading to some unburned fuel being expelled as exhaust. This inefficiency is compounded by environmental concerns, as they tend to generate higher emissions compared to their 4-cycle counterparts.

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.
