Scope of application
High-precision AC leakage current, current, high-order harmonic current, phase, electric energy, power, power factor, etc. detection
What to use with?
1. Multimeter (mA level current file)
You can directly view the current value after passing the transformer ratio, the standard configuration is 2500:1
For the measurement of direct current or alternating current, the indirect method is generally used.
The specific method is:
(1) First, the amount of current is transformed into a proportional voltage.
(2) Then observe with an oscilloscope. The general test method is: connect a non-inductive resistor with high accuracy and small resistance in series in the circuit under test, and then use the oscilloscope to measure the voltage, and the voltage across the resistor is effective. Calculate the measured current value, and the calculation formula is I=U/R. In the formula, I-the measured current value, A;∪-the effective value of the voltage at both ends of the series resistor, V; R-the resistance value of the series-connected non-inductive resistor, Ω.
