Figure 1 shows a schematic illustration of this scheme. There are two sources of prognostic cloud condensate, namely convective detrainment (samfdeepcnv_run() and samfshalcnv_run()) and grid-sale condensation (zhaocarr_gscond_run()). Both of them produce either cloud water or cloud ice, depending on the cloud substance at and above the grid point at current and previous time steps, and on the temperature. Evaporation of cloud is allowed at points where the relative humidity is lower than the critical value required for condensation. Precipitation is diagnostically calculated directly from the cloud water/ice mixing ratio. Both frozen and liquid precipitation can be prognostically produced, enabling this scheme to predict precipitation type.

REVISED I found the schematic for your module. A current transformer connected to it will definitely NOT damage the module. Also, if you believe their datasheet, the 30A device is a voltage output model.
knowledge points based on the platform. This experiment calls the common device library that comes with quartus, and uses the method of schematic drawing to simulate traditional experiments to verify various simple gate circuits, flip-flops and module circuits on a breadboard or experiment box. The experiment requires students to verify the functions of the 74LS138 and the 4-input 16-output decoder composed of 2 pieces of 74LS138 through the lower board and the instrument on the FPGA platform. The operation involved in the whole process is very basic, which can avoid the problem of poor reliability and flexibility of manual wiring.
Considering that the nail tip temperature quickly dropped after each initial peak in Fig. 4c, the local heat generation must be dramatically reduced. Local heat generation greatly depends on ISC current, so it is hypothesized that the nail tip temperature dropped due to abrupt decrease of ISC current. The 3-cell module was tested to validate this hypothesis. The module consists of three single cells connected in parallel as shown schematically in Fig. 2c. Ideally, the current distribution of each electrode layer in the single cell should be measured to determine variation of ISC current and test the hypothesis. But such measurement would require fabrication of special segmented cells,37,38 which is out of the scope of this work and will be done in future work. Considering that the electrode layers were connected in parallel in the single cell, their current distribution behaviors could be mimicked and indirectly characterized by current distribution behaviors of the 3-cell module.
The results and discussion above suggest that the dramatic decrease of nail tip temperature after each initial can be attributed to the abrupt drop of ISC current. Previous modeling results by Zhao et al.16 showed that ISC resistance significantly influences ISC current. It is hypothesized that the ISC current abruptly dropped due to dramatic increase of ISC resistance. To verify this hypothesis, a single layer cathode coated on aluminum foil was tested using the 3S nail penetration. The resistance was measured using a four probe method as schematically shown in Fig. 2d. A similar method has been used by Chen et al.31 recently to characterize static resistance after electrode and current collector foil were penetrated by a nail. Here the method is used to characterize transient variation of resistance during nail penetration of a cathode coated on aluminum foil. The results are shown in Fig. 9, including measured voltage drop across electrode and aluminum foil, current flowing through the nail and estimated short circuit resistance. It can be seen that the resistance was initially very high and gradually decreased as nail penetrated deeper into the cathode. Then the resistance abruptly dropped by several orders of magnitude, suggesting the nail touched the aluminum foil. But very quickly the resistance recovered to a level as high as before the sudden drop. A visual check of the cathode electrode and aluminum foil, as shown in Fig. 9c insert, suggested that the aluminum foil ruptured. Aluminum rupture would cause significant contact resistance increase between the aluminum foil and the nail. These results support the hypothesis that ISC current abruptly increased when nail tip touched aluminum foil and then quickly dropped due to dramatic increase of ISC resistance. It also suggests that the dramatic increase of ISC resistance can be attributed to rupture of aluminum foil. It took a long time for the cathode to rupture, which could be due to deformation of the single layer cathode.
Based on the results and discussion above, a mechanism is proposed to explain the behaviors of ISC and nail tip temperature during 3S nail penetration of the 3-Ah cell. The mechanism is schematically shown in Fig. 11. After the nail penetrates the first layer of copper foil, anode and separator, ISC would be formed and its development can be divided into three stages. In stage 1, the nail tip contacts cathode so that cathode is in short with copper foil and anode. High resistance of cathode material would limit the ISC current to a low level. Correspondingly, the increase of heat generation and local temperature are slow. In stage 2, the nail tip contacts aluminum foil so that aluminum foil is in short with copper foil and anode. The aluminum foil resistance is much lower than cathode materials. The contact resistance between aluminum foil and nail is also very small due to tight contact. The overall ISC resistance would be several orders of magnitude smaller than that in stage 2, leading to a very high ISC current flowing through the nail and aluminum foil around the nail tip. The high current causes rapid local heat generation and temperature rise. Due to the small thickness of aluminum foil, only 0.02 mm, it would be quickly penetrated by the nail and ruptured. The ISC would then enter stage 3. In this stage, the contact resistance between aluminum foil and nail becomes so large that the overall ISC resistance would be comparable to stage 1. In response, the ISC current and local heat generation would significantly drop. The local temperature at nail tip would also rapidly drop due to heat transfer to nail body and adjacent cell materials. As the nail penetrates deeper into the cell, similar processes would repeat, causing another large yet temporary ISC current and local temperature peak, as can be seen from Fig. 4c. Combined with thermal energy stored during previous ISC pulses, the local heat generation and temperature peak would become increasingly higher, eventually high enough to cause thermal runaway.
