Q1: What is a clamp-on current transformer?
A1: Clamp-type current transformer is a kind of detection device, that can feel the information of the measured current, and can detect the felt information. Clamp AC transformers according to a certain law into a certain standard need to meet the electrical signal or other required forms of information output, in order to meet the requirements of information transmission, processing, storage, display, recording, and control. For example, switching power supply, hard switch, soft switch, etc.
Q2: What equipment can be used with a clamp-on current transformer?
A2: Clamp-on current transformers can be used with multimeters (mA level current grade), oscilloscopes, and other instruments, and clamp-on AC transformers can also be used as current probes.
Q3: What are the advantages of sisco clamp-on current transformer?
A3: sisco clamp-on current transformer is a precision current transformer, which is specially designed for power field measurement and metering use characteristics. The clamp-on current transformer is made of high permeability material, high precision, strong anti-interference ability, etc. When using the clamp-on current transformer can be directly clamped on the bus bar or bus bar without cutting off the line power outage its use is very convenient.
Tips: How does the clamp-on current transformer work with an oscilloscope?
For DC current or AC current measurements, the indirect method is generally used.
- First the flow of electricity into a proportional amount of voltage.
- Then use the oscilloscope to observe, the general test method is:
In the circuit under test in series with a high precision, resistance value of a small non-inductive resistor, and then use the oscilloscope to measure the voltage method, the voltage across the resistor measured RMS value, and then calculate the measured current value, the calculation formula is: I = U / R. The formula I measured current value A, U series resistor voltage RMS value V, R series inductance resistor resistance value Ω.
