Current Shunt for DC Energy Meter
The fixed-value shunt is mainly used for the measurement of large currents. Its working principle is similar to that of a small-value four-terminal measuring resistor. It reflects the magnitude of the measured current by measuring the current voltage drop. AFL-T series fixed-value shunt is mainly made of manganese-copper material and copper terminals welded with silver alloy. The copper terminals on both sides have a set of current measurement terminals and voltage sampling terminals. The maximum rated current is 10kA, and the structure is ≤50A. The plastic base is fixed and installed, and when >50A is directly fixed and installed with copper terminals. When the shunt is used in conjunction with the pointer ammeter, since the ammeter is actually a millivolt meter with a resistance of about several ohms, it must be connected with a pair of fixed value wires supplied with the ammeter; when the shunt is matched with the digital voltmeter When in use, then can be connected with any wire.
