WebThere are two main types of asymmetrical faults: shunt type and series type faults. Shunt type fault is a connection between two network elements. Series type means broken connection at the conductor. The most common asymmetrical fault is an earth fault. Asymmetrical fault indicates itself easily and from the phase values it is easy to acquire ... 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 path.
