- The current probe is a magnetic ring designed to measure the interference current signal in the wire according to the Faraday principle. It is essentially a transformer with one turn. Use a current probe to measure the amount of current flowing through the wire. Current probes are divided into AC / DC current probes and AC current probes. The former can measure the magnitude of DC and AC current, while the latter can only measure the magnitude of AC current.
- The current flowing through the wire causes an electromagnetic flux field to form around the wire. Current probe is for sensing
- A current probe, also known as a current clamp, provides a safe, cost-effective, simple, and accurate way to measure current. They can measure current without breaking the circuit. The jaws of the current clamp can be opened to surround the conductor to form a magnetic field loop. Then measure the current. In practical applications, there are many parameters of current probes that need attention.
- 1.Nominal current
- Nominal current is the maximum current that can be measured by a current clamp. In actual applications, it is not allowed to measure such current for a long time. The unit is Ampere A, and it is divided into DC and AC.
- Although the current probe is not as common as the voltage probe of an oscilloscope, its role cannot be replaced by other probes. It can measure the current flowing through a wire without damaging the wire. When the current probe is used in conjunction with the voltage probe, it can test data such as power and phase. This is very useful for test and measurement systems.
