The 3D model of the mentioned wagon, made in a system of the CAD class, is shown in Fig. 1.
In the Fig. 1 are indicated areas of wagon paneling particularly susceptible to mechanical damage arising from the loading and unloading method of transported material as well as susceptible to damage resulting from the physico-chemical properties of the transported freight.
Inner paneling of wagon side walls Paneling of a wagon floor Inner paneling of front and rear walls Fig. 1.

The typical discharge spectrum of electrical equipment is shown in Fig.1.
Fig.1 Typical electrical equipment discharge spectrum Principle of UV Pulse Detection.
(1) Compared to UV power method, UV pulse method is more sensitivity and it’s easier to apply.
Therefore, setting sampling time as 0.2s, 0.4s, 0.6s, 0.8s and 1.0s, measures pulses frequency by every 10cm from 20cm to 90cm.

By increasing the wall-thinned depth from 0.25 to 0.75, the limit pressures at φ=π/6 decreased about 10~70% with a variation of the wall-thinned angles (2θ/π=1/4, 1/2, 1).
