Impulse Current Measuring Shunts
ICMS
The Impulse Current Measuring Shunts ICMS are new designed tubular shunt types with best response behavior to match the high performance of the TR-AS digital recorder for comparative current measurements. A 1st partial response time less than 10ns and a settling times less than 20ns show the advantage of these shunts. They show no initial overshoot peak, no oscillations and do not need compensation box to optimize the transient behavior as known from e.g. cage shunts.

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.
