Beschreibung
Zusammenfassung:	The invention provides an electric energy meter with a client short-circuit protection function, which comprises a relay, a short-circuit alternating-current signal amplification and absolute value full-wave rectification filtering module, a short-circuit signal threshold comparator, an OR logic module, a relay switch-out switch, a short-circuit current sampling manganese-copper resistor and a live wire current sampling manganese-copper resistor, wherein one end of the short-circuit current sampling manganese-copper resistor is connected with the live wire current sampling manganese-copper resistor, the other end of the short-circuit current sampling manganese-copper resistor is connected with the relay, and two input ends of the short-circuit alternating-current signal amplification and absolute value full-wave rectification filtering module are respectively connected with two ends of the short-circuit current sampling manganese-copper resistor; one end of the short-circuit signal threshold comparator is con
