Lightning Current Generator
-
Shanghai Guantu Technology Co., Ltd.
The lightning wave impulse current generator is an impulse current generator that generates a simulated lightning current waveform . Its working process is as follows: first, the transformer charges the capacitor bank through the silicon pile, when the charging voltage reaches a predetermined value, the spark gap is triggered, and the capacitor is discharged through the total inductance and total resistance of the circuit. When the resistance is greater than or equal to the critical damping value, a unidirectional impulse current wave is generated in the circuit. When the resistance is less than the critical damping value, an oscillating impulse current wave is generated. The magnitude of the impact current amplitude is related to the circuit parameters. When the capacitance value and charging voltage are the same, the smaller the inductance value, the greater the current amplitude. In order to obtain as much current as possible, a pulse capacitor with a small inductance value is usually selected, and the total length of the connecting line should be as short as possible when arranging the main capacitor, so that the total loop inductance value can be reduced as much as possible.

Current Sense Magnetics
-
Current sense magnetics are used as a low loss method for sensing AC current in a circuit and also provide electrical and safety isolation between the source of the current and the measurement circuit. The key parameters for a current sense transformer are the rms current rating (to ensure it does not overheat in the application) and the safety and voltage isolation (to ensure it conforms to the end-application requirements).

SparkFun Current Sensor Breakout
ACS723 (Low Current)
-
The low current version of the SparkFun Current Sensor Breakout is a high accuracy board that utilizes the ACS723 for low to moderate AC and DC current sensing applications. The ACS723 sensor uses a Hall effect sensor to output a voltage relative to the current flowing through the IP+ and IP- pins on the board. The advantage of using a Hall effect sensor, specifically, is that the circuit being sensed and the circuit reading the sensor are electrically isolated meaning that, although your Arduino is running on 5V, the sensed circuit can be operating at higher DC or AC voltages!
