Description

technical field [0001] The invention relates to a current clamp detection device and a detection method thereof, in particular to a current clamp detection device for automobiles and a detection method thereof. Background technique [0002] Usually, when using an ordinary ammeter to measure the current, the circuit needs to be cut off before the ammeter can be connected for measurement. In many cases, the equipment in normal operation does not allow this; at this time, the current clamp can be used to measure the current without cutting off the circuit. [0003] The advantage of the current clamp being able to measure live on-site makes it widely used in the automotive industry. The current clamp is a current transformer with the characteristics of an open and close magnetic circuit. The magnetic circuit of the current clamp can wrap the measured current line into the magnetic loop of the current clamp. After the magnetic circuit of the current clamp is closed, a current tr...
