WebOct 8, 2024 · 2.1 Shunt Tripping Scheme. This is the most commonly used tripping scheme. The protective relay (PR) contact is arranged directly to trip the circuit breaker and it simultaneously energises an auxiliary unit X which then reinforces the contact that is energising the trip coil. The scheme is shown in Figure 1. When a circuit must be protected from overvoltage and there are failure modes in the power supply that can produce such overvoltages, the circuit may be protected by a device commonly called a crowbar circuit. When this device detects an overvoltage it causes a short circuit between the power supply and its return. … See more In electronics, a shunt is a device that creates a low-resistance path for electric current, to allow it to pass around another point in the circuit. The origin of the term is in the verb 'to shunt' meaning to turn away or follow a different … See more A gas-filled tube can also be used as a shunt, particularly in a lightning arrester.
