After that, the leads of the Capacitor should be connected to the Multimeter probes and the readings on the Multimeter must be observed. In the beginning, the resistance will be low and then will gradually increase for a good Capacitor. For a shorted Capacitor, the resistance will low at all times.
For a good Capacitor, every attempt of the test should show a similar result on the display. If in the further tests there is no change in the resistance, then the capacitor should be replaced as it is a dead one. At first, the Capacitor must be disconnected from the circuit board and then it should be discharged completely.
Visual inspection of the capacitor bank must be conducted for blown capacitor fuses, capacitor unit leaks, bulged cases, discolored cases, and ruptured cases.

When the capacitor is in normal operation, there should be no noise. If you hear an abnormal "crack", "pop" discharge sound or "buzzing" annoying sound, it clarifies that there must be a shortcoming inside the capacitor, and the operation should be stopped immediately for further inspection or replacement of new products.
within 10 years after the railway structure is put into operation. If the results of special comprehensive inspection show the target structure has the required performance, the comprehensive inspection cycle may be extended accordingly. The process of tunnel inspection and maintenance is shown in Figure 2.
