The power system is equipped with a Class II/C SPD. Meanwhile, each module of the system has perfect lightning
protection circuit. The system can withstand simulated lightning surge currents of 20kA at 8/20μs five times, and 40kA
at 8/20μs once. To prevent higher lightning strikes from damaging the equipment, it is recommended to install a higher
protective Class I/B SPD in the cable inlet of the equipment room (lightning surge current is at least 60kA, refer to
YD/T5098-2001 Signal station lightning overvoltage protection engineering design standard).
To prevent lightning strikes at the DC side from damaging the equipment, an effective lightning protection device is
provided, which can withstand simulated lightning surge currents of 10kA at 8/20μs once respectively. To prevent
conductive lightning strike from damaging the modem port of the controller, the power system provides lightning
protection (optional) for the modem port. The SPD can withstand a 5kA lightning surge current at 8/20s and a 4kV
lightning surge voltage at 10/700s.
The power system has perfect lighting protection at both AC side and DC side. The power system is equipped with a
Class II/C SPD at AC side and SPD at DC side. To achieve better lightning protection at AC side, it is recommended to
mount a Class I/B SPD, lightning surge current is at least 60kA. The Class I/B SPD should be purchased by the user. Refer
to YD/T5098-2001 Signal station lightning overvoltage protection engineering design standard for the detailed technical
rules. The Class I/B SPD installation is shown in Figure 1.4.
