WebOverload protection is actually a protection against overheat due to the flow of overcurrent in the circuit for specific time. Slow blow fuses and overload relays are used against … WebJan 20, 2024 · This paper proposes an adaptive optimum overcurrent protection for deregulated distribution networks containing parallel feeders. The proposed adaptive coordination eliminates the maloperation of conventional overcurrent protection under different fault scenarios. These scenarios take place when faults occur close to the end … WebExplanation, Types & Applications. Overcurrent relays are used for protecting the equipment by over-currents. Over currents may cause the break in insulation if temperature exceeds the limits for which the insulation is designed. For wide varieties, these relays are used which are listed below.
