The working principle of the clamp meter ammeter: The clamp meter is mainly composed of the current transformer, clamp wrench and a commutating magnetoelectric system with a reaction force meter. According to the proportional relationship between the primary winding and the secondary winding of the current transformer, the rectifier can display the current value of the measured line.
A clamp ammeter is an instrument that combines current and ammeter. It's an important branch of numbers. It works on the same principle as measuring electricity. The clamp ammeter consists of current transformer and ammeter. You can open the core of the CT by tightening the wrench. No need to cut the wire through which the current is measured * It can pass through the gap where the core opens, and the core can be closed when the wrench is released.
Clamp ammeter is simple to use. To measure the current, you simply clip the wire to be tested into the clamp of the clamp ammeter and then read it on the digital display or indicator dial. Easy to use, just clamp the measuring wire can be. However, the widespread use of digital clamp ammeters has now added many multimeter features to clamp meters.
The working part of the clamp circuit meter is mainly composed of electromagnetic ammeter and pass-through current transformer. Through type current transformer is called clamp type ammeter because its core is made of movable opening. It is a portable instrument that can directly measure the AC current of a circuit without disconnecting the circuit. It is very convenient to use in electrical maintenance and has a wide range of applications.
